First-principles Study on the Ductility Effect of Zirconium and Its Distinct Behavior from Boron to Restrain Hydrogen-induced Embrittlement in Ni-Ni3Al AlloysYuxi WU and Yuanming WANG 1)Shenyang...,the occupation behavior and the ductility effect of zirconium in a Ni-Ni3AI system were investigated.It is found that zirconium has a stronger segregation tendency to Ni region than to Ni3Al region.The bond......
First-Principles Study of the Influence of Lattice Misfit on the Behavior and the Ductility Effect of Hafnium in Ni-Ni3Al SystemYuxi Wu1,Jia Guo1,Jieshan Hou2,Wanglin Zhang1,Renzhong Huang3,Xianguo... the segregation behaviors of Hafnium(Hf) and explore the influence of lattice misfit on the ductility effect of Hf.It is found that though Hf prefers to substitute Al rather than Ni in Ni3Al phase within most......
The simultaneous improvements of strength and ductility in additive manufactured Ni-based superalloy via controlling cellular subgrain microstructureYanan Zhao1,Zongqing Ma1,Liming Yu1,Ji... terminate the motion of dislocation during the plastic deformation process,which contributes to increasing the strength as well as holding the stable plastic flow.Hence,the strength and ductility......
and impact ductility of 5CrNiMo steel using three different additions of RE La element is studied in this paper. The mechanical properties of 5CrNiMo steel with RE La additions are be compared with that of the 5CrNiMo steel on the same heat-treatment condition without RE La element addition. The results show that the strength. hardness and impact ductility of 5CrNiMo steel will be improved......
