Academic Achievements

Prof. Zhu has pioneered innovative ways to TEM-based identity techniques to study the relation between composition/microstructure and properties/performance of a wide range of materials (iron and steel, alloys, ferroelectrics and multiferroic materials, nano-materials, etc) and to carry out the practical results.


Study the properties of a wide range of materials, and to carry out the practical results.

From the late 1960s to late 1980s, ZHU Jing had worked on “Ageing structure and principle of strengthening-toughening in maraging steel” and “Research and development of maraging steel for centrifugal machine”. By mainly using electron microscopy and related process study, Jing had determined the ageing structure related with Co-Mo interaction and the evolution of phase stability, suggested and proved the effect of reversed austenite with highly dispersion on strengthening-toughening, and made clear the cause of embrittlement introduced by a high-temperature and slow cooling treatment in maraging steel. Based on these research results the alloying principle and a rational heat treatment system have been proposed, which have been applying use in the maraging steel served as the material of the centrifugal machine for uranium in China.

ZHU Jing has been working on intermetallics and superalloys. The stress introduced phase transformation in two-phase TiAl intermetallic alloys was experimentally found; and the borron on the charge density distribution in Ni3Al was experimentally studied by the TEM-CBED method to explain why the strength-toughness is improved in Ni3Al with B dopping from the point of view of electron structure. Jing’s research group had found, in a Re-doping nickel-based single-crystal superalloy, that three types of interfacial protrusion on the γ/γ’ interface formed by dislocation climb, co-segregation of Re with Co and Cr was observed at the tips of protrusions at the γ/γ’ interface, edge a/2<110> dislocations in the γ/γ’ interfacial dislocation network have a Lomer–Cottrell core configuration and edge a<100> dislocations also possess a non-compact core structure; as a result of coupling between interfacial dislocation motion and the co-segregation of Re with Co and Cr, together with these non-compact dislocation core structures, assisting stabilization of dislocation networks, the creep rate in the steady creep regime is slowed. Such results in atomic scale both for atom positions and species of the element, are rare both for fundamental of materials science and practical materials

ZHU Jing had been working on nano-materials and nano-structures research. The book in Chinese edition written by ZHU Jing et al was published in 2003. A size dependence of Young’s modulus, both bending and uniaxial tensile modulus, in ZnO nanowires (NWs) had been experimentally and theoretically studied and quantitatively revealed by ZHU Jing's group, it is indicated that the Young’s modulus of ZnO NWs with diameters smaller than about 120 nm increases dramatically with decreasing diameters, and is significantly higher than that of the larger ones whose modulus tends to that of bulk ZnO as well as the meso-mechanics still work as the diameter of ZnO nanowire larger than about 12 nm. Her group another nano-research work “Fundamentals, Fabrication and Applications of Silicon Nanostructures” is also worth commended in this field.

ZHU Jing has been working on the ferroelectric, the coupling effect and synergistic measurement of multiferroic order parameters in multiferroics since1999 and 2011, respectively. Jing’s group showed a physical picture about the chemical ordered domain and polar nanoregion in the relaxor type ferroelectric PMN and proposed that the behalf of Mg in PMN is very similar to that of Sn in BTSn(BaSnxTi1-xO3), both Mg and Sn present no covalent bonding effect with O, while Nb 4d–O 2p, Ti 3d-O 2p hybridization is enhanced through ferroelectric transition, there is strong compositional fluctuation of the Mg/Nb (Sn/Ti) ratio in PMN (BTSn), the Mg (Sn) atoms are mainly concentrated outside polar nano regions (PNRs) while the Nb (Ti) are concentrated inducing the generation of PNRs, and further increasing in the polarization by crystal lattice strain.. Her group first time demonstrated and defined a hierarchical micro-/nano-meter scale domain structure in PMN-xPT (x=0.32-0.33) single crystal near morphotropic phase boundary (MPB) in 2006. About size effect of ferroelectricity, the multi-phase (C, T, O and R phases) coexistence in a single BaTiO3 nanoparticle was revealed and a temperature-size phase diagrams were drawn by Zhu’s group, it is shown that BaTiO3 transforms from single phase to multi coexistent phases and the Tc increases significantly as the size decreases from bulk to nanoscale. Whereas it is different from the thickness dependence of the ferroelectric- paraelectric phase transformation in thin film that the free standing BaTiO3 thin film loses its ferroelelctricity when thinner than 4.4–4.8 nm found by her group. Zhu’s group and co-works revealed the forbidden nonsixfold ferroelectric domains surrounding the vortex cores in single phase multiferroics h-YMnO3 single crystal, the unanticipated symmetry breaking was observed at both mesoscale (domains) and atomic scale (vortex cores) due to the intertwining of two types of topological defects, i.e., (anti)vortex cores and partial edge dislocations. And they manipulated the different self-assembling strain-induced in-plane periodic domain structure in h-YMnO3 films, which influences the strain-accommodated properties and the resulting rich magnetic states, ferromagnetic-antiferromagnetic, ferromagnetic-spin glass-antiferromagnetic, etc. By in situ TEM observations it is well explained that the origins of double PE hysteresis loop and enhanced piezoelectric response are attributed to the electric-field induced reversible phase transition at the MPB region in the Sm-doped BFO system by Zhu’s group.

2007-2012 Prof. Zhu was leading an industry-academy-research cooperation group to research and to develop the domestic hollow axles of trains in high speed railway. The “material selection and manufacturing of the hollow axles” acquired 4 China invention patents which won “Invention Entrepreneurship Award”-gold award in 2016.


Explores materials based on the solid physics and chemistry basis.

The coherent electron wave micro diffraction effect of an individual atomic planar fault was found and defined for the first time in the world by Jing’s observation using the cold field emission gun scanning transmission electron microscope in U.S. and analysis with kinematical diffraction theory in 1982. This novel technique has extended to study on stacking faults, twins and GP zone in Al-4%Cu. An intergrowth of muscovite and biotite from Mitchell Creek Mine, Upson County, Georgia US, was studied with HRTEM. Atomic arrangements of the interface between muscovite and biotite have been derived, revealing far more complexity for the interface structure than that proposed previously based on optical and X-ray analysis. Through the study of the electron energy loss near-edge structure of the K-edge of Mg and Al octahedrally and tetrahedrally, respectively, coordinated by oxygen, tetrahedrally coordinated Si, K and oxygen, the rearrangement process caused by radiation damage of the intergrowth of muscovite and biotite had been investigated and demonstrated. The appearance of a small peak below the threshold of the K-edge of oxygen is interpreted as due to a valency of oxygen between zero and -2. ZHU Jing was organizing a team, the members of which experienced oversea study of advanced electron microscopy after the Culture Revolution to write the book (1987, in Chinese edition) for stimulative closing the gap in electron microscopy field between China and the western countries.

Electron magnetic chiral dichroism (EMCD) opens a door to explore magnetic properties by transmitted electrons. However, obtaining quantitative magnetic parameters undergo a long way along with the development and improvement of this technique both in theoretical and experimental aspects. Since 2009 ZHU Jing's group has been developing the quantitative EMCD technique to measure magnetic parameters with spin-, element-, site-specificity and orbital-spin-specificity as well as to apply to quantitatively determine atomic site specific magnetic structure information, such as site-specific total magnetic moments and orbital to spin magnetic moment ratios on a nanometer scale in NiFe2O4, YIG, STO/LaMnO and etc. An approach that allows in-plane magnetic signals to be measured using EMCD to determine the intrinsic magnetism of thin samples was proposed. The new record of spatial resolution for EMCD has recently reached atomic-plane resolution by introducing the chromatic-aberration-corrected TEM.
