Microstructure and texture evolution of Mg–3Zn–1Al magnesium alloy during large-strain electroplastic rolling

International Journal of Minerals,Metallurgy and Materials 2015年第4期22卷 411-416页

作者： Yan-bin Jiang Lei Guan Guo-yi Tang Bo Cheng Da-bo Liu Key Laboratory for Advanced Materials Processing of the Ministry of Education Institute of Advanced Materials and Technology University of Science and Technology Beijing Beijing Institute of Aeronautical Materials Aviation Industry Corporation of China Advanced Materials Institute Graduate School at Shenzhen Tsinghua University

Large-strain deformation by single electroplastic rolling （EPR） was imposed on AZ31 magnesium alloy strips. During EPR at low temperature （150-250℃）, numerous twins formed in the alloy. After EPR at a high temperature （350℃）, the number of twins reduced and some dynamic recrystallization （DRX） grains formed at grain boundaries and twinned regions. The synergic thermal and athermal effects generated by electropulsing, which promoted dislocation motion, induced a few small DRX grains, and ductile bandings were mainly re- sponsible for large-strain deformation during EPR. The inclination angle of the basal pole stemmed from the counterbalance of the inclina- tion direction of the basal pole between the DRX grains and deformed coarse grains.

Study on the bonding strength and thermal shock resistance of thermal barrier coatings regulated by interface texture

Surface and Coatings technology 2025年 512卷

Regulating the microstructure of thermal barrier coating interfaces is an effective approach to enhance the thermal stability of the coatings. In this study, high-energy beam laser was used to texture the interface between the bond coat and the ceramic coat (circumferential type, Class C; Kagome type, Class K). The tensile bonding strength and strain capacity of the textured thermal barrier coatings were higher than those of the non-textured coatings. Texturing increases the unit contact area ratio (U) at the interface between the bond coat and the ceramic layer, which helps the coating resist thermal stress impact, reduces the spallation area ratio (Sar) and the spallation rate. Among them, Class C texture can effectively delay the rate of microcrack propagation, while Class K texture has a dual effect of circumferential restraint and suppression of inelastic deformation at the interface. The Kagome-type (Class K) textured coatings have a lower spallation rate than the circumferential-type (Class C) textured coatings. The coating with K2 interface texture exhibits the best thermal shock resistance, with a surface spallation area ratio of only 9.38 % after 120 thermal shock cycles; whereas the non-textured coating has a spallation area of about 13.7 % after the same number of thermal shock cycles. This research provides potential application value for the regulation of interface stability in thermal barrier coatings.

Physically-based cloth animation has been a hot topic to the graphics community for more than a decade. Among the physically-based models used in cloth animation, elastically deformable models have been used successfully in order to give a representation of the behavior. We present a novel PCMS (Predictive-Corrective Mass-Spring) algorithm in cloth simulation which combines the advantages of both BMS and an advanced numerical integration method, namely low computational costs and large time steps. The numerical and rendering results show that a speed-up of more than an order of magnitude over the commonly used mass-spring method while the simulation results are in agreement with real cloth behavior. In addition, the super-elastic effect will be effectively controlled without dynamic inverse constraints on deformation rates. © 2010 IEEE.

One of the most important problems of airplane infrared simulation is to establish the simulation model accurately based on real-time status. This paper analyses the three main sources of infrared signatures in airplane: airplane-skin, nozzle components and exhaust plume. By reckoning environment radiation, aerodynamic heating, heat transferring and hot engine casing principle, a synthetic simulation method was used, especially a new infrared engine model for airplane was firstly proposed with airplane's working status as the input. Then atmospheric transmittance is analyzed through Modetran4 with various influential factors such as atmospheric aerosol and geometric path considered. Finally the simulation results obtained have been analyzed with respect to different work status and view angle parameters, which will have an important effect on infrared image simulation system in military simulation system. © 2010 IEEE.

Exploring and manipulating the orbital degrees of freedom in solids has become a fascinating research topic in modern magnetism. Here, we demonstrate that spin waves can provide a way to control electronic orbital magnetism by the mechanism of scalar spin chirality, allowing for experimental detection using techniques such as the magneto-optical Kerr effect and scanning transmission electron microscopy. By applying linear spin wave theory, we uncover that electronic magnon-driven orbital magnetization is extremely sensitive to the character of the magnonic excitations. Furthermore, we show that both the induced electronic orbital magnetism and the Nernst transport properties of the orbital angular momentum can be regulated by the strength of the Dzyaloshinskii-Moriya interaction, Kitaev interaction, as well as the direction and magnitude of the external magnetic field. We argue that magnon-mediated electronic orbital magnetism presents an emergent variable which has to be taken into account when considering the physics of coupling magnonic excitiations to phonons and light. © 2025, CC BY-NC-SA.
