Phase-field simulation of phase separation in Ni75AlxV25-x alloy with elastic stress LI Yong-sheng(李永胜), CHEN Zheng(陈 铮), LU Yan-li(卢艳丽), WANG Yong-xin(王永欣) State Key Laboratory... incorporated with the elastic stress was investigated using the microscopic phase-field model. The final morphology of γ′ and θ is similar in spatial alignment, but the volume fraction of γ′ phase increases......
concentration and it will give rise to crackles. More serious stress concentration will be produced with the quicker strain rate (or the lower stress temperature) and the crackles will expand... the boundaries with increasing strain rate, which produces the critical stress concentration. So the material will have ruptured as there’s not enough time to cause the dynamic recrystallization with the higher......

×10-6 s-1. The lowest one is under the condition of 1×10-5 s-1. Stress concentration and anode dissolving around Al-Fe-Mn intermetallics initiate micropores which will result in microcracks...Investigation of Stress Corrosion Cracking Initiation of 7A52 Aluminum Alloy李奇Department of Equipment Remanufacture Engineering, Academy of Armored Forces Engineering摘 要:
concentration caused by normally distributed heterogeneities in heterogeneous materials. The results show that the maximum subsurface von Mises stress of homogeneous material under a given load increases when friction coefficient becomes larger. Location of the maximum von Mises stress changes due to the existence of distributed heterogeneity elements. Subsurface stress concentration of the matrix becomes......
