Adhering to the concept of "aiming at applications", he led the team to make "magnesium" and "magnesium alloy" continue to be gorgeous "transformed", so that China's lightweight magnesium technology expands the application field and goes to the world, and realizes a significant reduction in equipment components from mobile phone shells to aerospace. Ding Wenjiang, an academician of the Chinese Academy of Engineering and a professor at the School of Materials Science and Engineering of Shanghai Jiao Tong University, has formed three firsts in the world's magnesium alloy research: the first in the total number of published papers; the first in the number of invention patents; and the first in the number of applied components and development capabilities. In October this year, Ding Wenjiang was elected as the "Most Beautiful Science and Technology Worker" in Shanghai in 2021.
Rich experience hones keen insight
Ding Wenjiang has rich experience, from the age of 16 to Jiangxi farming with knowledgeable youth, to 1981 graduated from Shanghai Jiao Tong University casting major, from the factory to the university, he has served as vice president of Shanghai Jiao Tong University, deputy director of Shanghai Municipal Science and Technology Commission, vice chairman of Shanghai Municipal Association for Science and Technology and other positions, in a number of academic groups as chairman, vice chairman, vice president, standing director and other positions.
Since engaging in scientific research, Ding Wenjiang has been engaged in research on light alloy materials and their molding technology. In 1986, he was invited by the Technology Development Center of Mitsubishi Light Metals Corporation in Japan to be a senior visiting researcher, engaged in the development of aluminum matrix composites, proposed a new melt preparation method for Mitsubishi Company for particle-reinforced aluminum matrix composites and applied for a patent, which was highly praised and tried to retain him to work in Japan. However, he politely refused the good intentions of the Japanese side and resolutely returned to China to continue teaching and scientific research.
In terms of light alloy research, Ding Wenjiang has always adhered to the concept of "aiming at application" and believes that "'useful' is the soul of material research". His visit to Japan has broadened his horizons and identified that light alloys will be an important direction, especially magnesium alloys as the lightest, resource-rich structural materials will inevitably be of great use, thus becoming one of the pioneers in advocating and engaging in magnesium alloy research in China.
At the end of 1987, he returned to China to participate in the localization of the magnesium alloy gearbox of Shanghai Volkswagen Santana car, invented the foamed magnesium alloy covering agent, replaced the imported flux and was applied in the production of the car gearbox shell, making an important contribution to its localization. He has a keen insight into key technologies and key areas in light alloy research, and has made breakthrough research results on some major needs.
Let the magnesium gorgeous "transformation" continue to expand the field of application
Magnesium has the smallest specific gravity among practical metal structural materials (2/3 of aluminum, 1/4 of steel). This feature is of great significance for the weight reduction of hand-held products in modern society, the reduction of energy consumption of vehicles, and the reduction of the weight of important equipment. Ding Wenjiang led the team, from the mobile phone shell to the large and complex components of the aircraft, to achieve a significant reduction in equipment weight, and promoted China's magnesium technology and products to the world.
He combined China's two superior resources - magnesium and rare earths, created 5 new high-performance magnesium alloys, developed more than 10 new processing technologies and equipment, and developed more than 50 key important components. Ding Wenjiang and the team continue to study, many times to make "magnesium" and "magnesium alloy" gorgeous transformation, greatly expanding and extending its application field. After continuous efforts, they have made the "flammable" magnesium no longer flammable, significantly reduced environmental pollution, and realized the transfer and industrialization of magnesium and aluminum alloy auto parts manufacturing technology; so that the "soft" magnesium is no longer soft, expanded the scope of use of magnesium alloys, and implemented the industrialization demonstration project of high-quality magnesium alloys and their products; so that the "unstable" magnesium alloys are no longer "active" and realize the precision molding of a variety of important components equipped with heaven and earth.
Ding Wenjiang research materials adhere to the concept of "materials to the fullest, go with the flow", he makes full use of the magnesium alloy as a structural parts of the lively "shortcomings", to achieve a leap from structural materials to functional materials, the development of a series of magnesium-based biomedical materials, magnesium-based energy materials and magnesium-based agricultural materials, etc., greatly expanding the application field of magnesium materials.
The research of Ding Wenjiang's team also provides advanced products for the development of internationally renowned companies such as General Motors, Hitachi, and Boeing in the United States, which have achieved high international influence and promoted China's magnesium technology and products to the world.
To create "China's magnesium industry best talent cultivation base"
"I've always believed that in team building, the first priority is to educate people." Ding Wenjiang said that he asked team members to strive to improve in four aspects: realm, mind, ability and passion. The second is that the team must have a common vision, and the common vision of his team building is "one of the most cohesive research teams in Shanghai Jiaotong University", "the best talent cultivation base in China's magnesium industry", and "one of the most competitive bases for magnesium research in the world".
He vividly described the development process as the three stages of "eating - eating well - eating happily". "Eating" is for the survival stage, "eating a good meal" is a well-off stage, "eating happily" everyone can work efficiently and get along happily, and they are happy and harmonious.
He always asked himself and his team members to achieve 4 "n's", which were both irritable, attractive, introspective, and introverted. He attaches special importance to the construction of the team of innovative talents, and forms a set of talent training, introduction, use, evaluation and incentive mechanisms within the team to maximize the enthusiasm for innovation of scientific and technological personnel. His team has a number of young professors and researchers under the age of 40, and has achieved excellent results in the research of light alloys.
"To be a person and do learning, you must have some blunt sensitivity"
"To be a person and to do learning, you must have some blunt sensitivity." According to his team colleagues, Ding Wenjiang has repeatedly talked with his colleagues about the book "Blunt Feeling" written by Japanese writer Junichi Watanabe, "blunt feeling" is to learn to tolerate, absorb, tolerate and bland, often become a big thing mostly people who are not "preoccupied". Ding Wenjiang likes to read, has a wide range of involvement, and is good at summarizing, every time he reads a good book, he will exchange his experience with the backbone of young people.
"Scientific research must do effective scientific research, and being able to innovate, make technical prototypes, and do development are all effective scientific research." And there is neither originality nor effect, just imitation, reproduction, this is a completely ineffective scientific research. Ineffective scientific research costs a lot of manpower and material resources, but it cannot inspire people and cannot promote economic development", and if you want to make "effective scientific research", Ding Wenjiang said that "calming down" is the primary quality that should be possessed. Continuous in-depth research and hard work in a field, and long-term enjoyment, so that it can be rooted in the roots. Especially in the field of engineering, we should pay more attention to the needs of the country and the development of people's livelihood, and closely integrate academic research and the development of productive forces, so that there is more room for development.
"Yu is proficient in materials, materials must be made of materials, materials must be made into instruments, and instruments should be easy to use", these 16 words embody the unremitting pursuit of a material person for decades. Ding Wenjiang has achieved the organic integration of basic research, application development, engineering research and technology transfer.
Under his leadership, after more than ten years of development, today's National Engineering Research Center for Precision Forming of Light Alloys has become an important research and development base for magnesium alloy materials in China and one of the largest and most advanced magnesium alloy research teams in the world. This team has made remarkable achievements in scientific research, platform infrastructure construction, team building and talent training, international cooperation and exchanges, and industrialization of achievements, especially in high-performance magnesium rare earth alloy materials, bionic functionalization of metal materials, magnesium-based degradable biomedical materials, magnesium-based energy materials, etc. Have completed a number of international advanced level research results, and published a number of influential academic papers in international first-class journals. And for the national major projects to provide a number of key materials and lightweight high-strength components. In the past five years, the cumulative output value of scientific research achievements to achieve technology transfer and industrialization has reached more than 500 million yuan, and Professor Ding Wenjiang, as the leader of the team, has greatly promoted the development of magnesium alloy research in China and even in the world.
In the scientific research position facing the world's scientific and technological frontier, facing the major needs of the country, facing the main economic battlefield, and facing the people's life and health, the team of academician Ding Wenjiang is still moving forward.
