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......
. The comparison of material grain size before and after ECAP was performed by applying the technique of electron back scattered diffraction(EBSD). The results show that the grains in the material after ECAP are refined and the yield stress and ultimate strength are increased. In order to investigate the deformation mechanism during ECAP and the reason for driving grain size refinement, three......
Characterization and photoluminescence properties of ultrafine copper molybdate(α-CuMoO4) powders prepared via a combustion-like processMohamed Benchikhi1,2,Rachida El Ouatib1,Sophie... grain size increased with increasing annealing temperature. The as-prepared CuMoO4 crystals showed a strong green photoluminescence emission at room temperature under excitation at 290 nm, which we......
ON THE MONTE CARLO SIMULATION OF NORMAL GRAIN GROWTH L.J.Wang1,X.F.Ma1,Y.T.Liu1,X.M.Shen1,X.J.Guan1 (1.School of Materials Science and Engineering,Shandong University,Jinan 250061,China) Abstract:The microstructures and their kinetics of normal grain growth are simulated using different Monte Carlo (MC) algorithms.Compared with the relative figures and the theoretical normal grain growth......
Effect of Milling Time on the Microstructure and Tensile Properties of Ultrafine Grained Ni–SiC Composites at Room TemperatureHefei Huang1,Chao Yang1,Massey de los Reyes2,Yongfeng Zhou1,Long... measurements. The TEM results showed well-dispersed Si CNP particles, either within the matrix, between twins or along grain boundaries(GB), as well as the presence of stacking faults and twin structures......
