激光增材制造Ti6Al4V/NiTi仿生功能梯度材料的界面特征及性能
TG456.7; 采用激光增材制造技术制备了组织致密且无缺陷的Ti6Al4V/NiTi仿生功能梯度材料(bionic function graded materials,BFGM),并对其界面微观结构、析出相特征和力学性能进行了研究.结果表明,Ti6Al4V/NiTi BFGM呈现由多种晶粒形貌和不规则异常共晶组织组成的非均匀组织,主要为富钛和富镍的固溶体以及(Ti,Ni)化合物.随着NiTi合金含量增加,不同沉积层中析出相的数量和形态发生了显著变化.BFGM的显微结构发生了一系列转变:α + β双相组织→柱状晶 + 不规则共晶结构→柱状晶→等轴晶→等轴晶 + 柱状晶.凝固过程中的相聚集、分离...
