Electrical Properties and Grain Growth Kinetics of PZN-based Ceramics Using Microwave Sintering CHOU Chen-chia1,LI Chen-liang1,M. B. Suresh1 (1.Advanced Ceramics Laboratory, Department... at 800℃ for 2 h. The small grain growth exponents indicate how easy the grain growth in these materials sintered using microwave radiation. Grain growth rate increases abruptly and is higher than......
of liquid alloy. Key words: AZ91D magnesium alloy; microstructure; semi-solid die casting process; morphology ... to be in equilibrium, and some zigzag surface is replaced with smooth one by the effect of interface tension and the surface energy of liquid on unmelted α-Mg grain boundaries. At this temperature, larger fusion......
morphology. This study proposes four-stage evolution process based on the shear stress-strain curve. During the shear process, coral sand particles slide and rotate within the interaction band, causing... the roughness of slabs is, the larger the shear stress is, the more obvious the contraction effect is and the more the particles break. Furthermore, the change in particle’s 3D morphology during......

and homogeneous microstructures can be obtained, the average grain size of the as-solid solution treated and as-aged composites after extrusion is under 3.0 μm. A large amount of the Cu-rich phase... homogeneously distribute inside the grains and at the grain boundaries. The ultimate tensile strength of the composite treated at T6 state, i.e. solid solution treated at 475 ℃ for 1 h then aged at 120......
