改善45结构钢切削性能的研究秦哲1,孙彦辉1,蔡开科1(1.北京市北京科技大学 冶金与生态工程学院)摘 要:开展了向中碳45结构钢中加入S,Ca元素来改善切削性的研究.研究结果表明:钢中w([S])=0.06%,总钙w(T[Ca])=40×10-6,w([Al]s)=0.01%左右时,夹杂物的纺锤率为57%;小于2.5μm的夹杂物数量占夹杂物总数82%,夹杂物呈细小,弥散状态分布于钢中.由热模拟试验得出钢的塑性转变温度在1 100~1 000℃,通过配水软件计算出二冷各区的冷却水流量并应用于生产,铸坯表面和内部......
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......
as those with Schmid factor greater than 0.45) in the sample. Additionally, it is found that the anisotropy in tensile ductility is in general agreement with a Considère criterion analysis... annealing; mechanical anisotropy; yield drop; ductility 1 Introduction Aluminum with an ultrafine-grained (UFG) structure is of interest for structural applications on account of its enhanced strength......
