Major achievements
achievements in scientific research
From the end of 1960s to the end of 1980s, Zhu Jing mainly used electron microscope to determine the evolution of aging precipitation structure and phase stability related to Co-Mo interaction, put forward and verified the toughening effect of high dispersion reverse austenite, and found out the reason of embrittlement after slow cooling at high temperature. On this basis, the boron-free alloying route and high molybdenum and low titanium heat treatment system were successfully implemented in China uranium separation steel.
In the early 1980s, Zhu Jing discovered and determined the properties of single domain boundaries and surface defects of single atoms with ordered structures in the United States by using the experiment and principle of coherent electron wave micro-diffraction, and the original papers published were cited as pioneering documents in this field. In the study of intermetallic compounds, she found the stress-induced phase transition of TiAl at room temperature; It is found that there is a disordered region rich in boron and nickel near the grain boundary of Ni3Al, which is beneficial to improve its plasticity. Through experiments and electron crystallography analysis, the different electronic structures caused by boron in Ni3Al and Co3Ti and their reasons are clarified. She also led the research team to systematically study the structural evolution of rare earth-doped single crystal nickel-based superalloy for aero-engine blades during creep, revealing the formation, dislocation configuration and classification of various convex structures at γ/γ' phase boundary. At the beginning of the second stage of creep, it is revealed and put forward that the segregation of rare earth elements and the dislocation at γ/γ′ phase boundary couple to form Lomer_Cottrellcore structure, which hinders the dislocation movement and prolongs the creep life. The unlocking phenomenon of Lomer_Cottrellcore structure in the third stage of creep is revealed.
Zhu Jing's research group made its own in-situ device, studied and measured the quantitative relationship between the diameter of one-dimensional ZnO nanowires and Young's modulus (bending and tensile modulus) by in-situ electron microscopy, proposed a core-shell model based on mesoscopic mechanics, and verified the core-shell model formed by the center and surface relaxation layer of nanowires from atomic scale by spherical aberration correction electron microscopy. The relationship between the size of one-dimensional nanowires and the experimental Young's modulus is quantitatively explained and verified. It shows that the mature mesoscopic mechanics theory is still valid when the diameter of ZnO nanowires is greater than 12 nm. She and her students have done influential work in the preparation and application research of silicon nanostructures.
In the research of ferroelectric materials, Zhu Jing's research group expounded the physical picture of ordered domains and nano-polarized domains in relaxed ferroelectric PMN(PbMgXNb 1-XO3), and expounded the geometry, composition and source of nano-relaxed polarized domains in BST(BaTi( 1-x)SnxO3) from the atomic scale, and calculated and analyzed the. The multi-level domain structure near the quasi-isomorphic phase boundary component in PMN- platinum single crystal is revealed and defined for the first time. The size effect of ferroelectric properties of barium titanate nanoparticles and films with different sizes was revealed, and the size-temperature phase diagram of barium titanate nanoparticles was drawn.
Since 2008, Zhu Jing has taken the lead in developing spherical aberration correction electron microscope-sub-angstrom scale material characterization technology and its application research in China. Her research group has carried out the research on the coupling effect of ferroelasticity, ferroelectricity and ferromagnetism in multiferroic materials, and explored the collaborative measurement method of multiferroic order parameters. Symmetry breaking, which was thought impossible in the past, was found in h-YMnO3 single crystal, and non-six-petal domain structures appeared, such as two-state, four-state and eight-state domains. The edge dislocations at the domain core coupled with the ferroelectric vortex domain core introduced an uneven strain field, which led to the transformation of the intrinsic six-state domain structure into a vortex domain structure with other order parameters. By controlling the oxygen partial pressure and selecting groups to grow H-YMNO _ 3 thin films, her research group regulated and realized the formation of self-assembled periodic domain structure in thin films caused by strain related to oxygen partial pressure. The magnetic states related to strain modulation are obtained, such as the existence of ferromagnetic-antiferromagnetic * *, and the existence of ferromagnetic-spin glass-antiferromagnetic * * *. In the aspect of quantitative measurement of high spatial resolution magnetic structure, her research group proposed a method of quantitative measurement of high spatial resolution magnetic structure with occupation resolution and atomic plane resolution by means of chromatic aberration correction of transmitted electron beam, and realized quantitative measurement of element magnetic moment and orbital/spin magnetic moment ratio in some thin film material systems; They also put forward the measurement method of in-plane EMCD, and realized the quantitative measurement of the intrinsic magnetic structure of the sample with the above developed method. Wait a minute. Her research team also carried out research on the surface structure, strain and composition distribution of precious metal-based catalysts and other materials.
During 20/200712, Industry-University-Research group headed by Zhu Jing developed hollow axles for high-speed trains in China, and "Axle Materials, Heat Treatment and Manufacturing Technology for High-speed Trains" won four China invention patents, and won the first prize in the 20/200716 Innovation Competition and the gold medal in the "Invention and Entrepreneurship Award-Project Award" respectively.
According to official website, Tsinghua University Institute of Materials, in July 20 19, Zhu Jing published about 300 academic papers in academic journals such as Science, PRL, NanoLetters, AdvancedMaterials and Angew. Chemistry, ActaMaterialia and so on. He also participated in editing China's first monograph on Analytical Electron Microscope, High Spatial Resolution Analytical Electron Microscope, Nanomaterials and Devices, and compiling monographs such as Structure and Characteristics of Material Interface, Progress of Transmission Electron Microscope, Nanowires and Nanowires-Materials, Properties and Devices, Volume II: Nanowires and Functional Materials. Obtained six national invention patents.
Official website, Tsinghua University Institute of Materials, July 2065438+2009 shows that Zhu Jing was invited to give a general meeting report and a special report of the branch at international academic conferences for more than 30 times.
personnel training
Zhu Jing suggested that students should listen to more lectures and broaden their horizons. She emphasized the importance of learning basic courses well and cultivating practical ability. Only by laying a good knowledge foundation can they accumulate wealth in future scientific research work. For material science researchers, good experimental operation ability is also essential; She thinks that the network resources are very rich and a good medium for acquiring knowledge, but she hopes that students will not indulge in online games and neglect their studies. She hoped that the students would cherish the golden years of their youth, make full use of various resources in Tsinghua, study hard scientific knowledge and make their own contributions to the development of China's material industry.
Zhu Jing thinks: The weakness of fame and team spirit is what we hope very much now. We have to do it ourselves, and we hope all young people will do the same, whether it is Bole or Ma, or how to promote talents and cultivate young teams.
According to the official website of Tsinghua University Institute of Materials (2065438+July 2009), among the graduate students trained in Zhu Jing, many won the National Top 100 Doctoral Dissertation Awards in Beijing and Tsinghua University.
