Simulation of facet dendrite growth with strong interfacial energy anisotropy by phase field methodYUAN Xun-feng(袁训锋)1, 2, LIU Bao-ying(刘宝盈)1, LI Chun(李春)2, ZHOU Chun-sheng(周春生)2, DING Yu-tian(丁雨田)3... of the facet dendrites increases linearly. The facet dendrite growth has controlled diffusion and kinetics.Key words:phase field; facet dendrite; hcp materials; interfacial energy anisotropy......
, the shear fracture preferentially occurs as the stress anisotropy coefficient increases. Both the maximum tensile stress and equivalent maximum shear stress decrease as the stress anisotropy coefficient increases, which indicates that the greater the stress anisotropy coefficient, the higher the external loading required to propagate a new fracture. The numerical results obtained in this paper provide......
Effect of Y and Ce on the microstructure, mechanical properties and anisotropy of as-rolled Mg-8Li-1Al alloyFeng Zhong1,Huajie Wu1,Ruizhi Wu3,4,Jinghuai Zhang1,Legan Hou1,Milin Zhang11. Key... properties and anisotropy of as-rolled Mg-8 Li-1 Al(LA81) alloy were studied. The combined addition of Y and Ce improves the mechanical properties with a low plasticity loss by solution strengthening......
