贫双相不锈钢2101(LDX 2101)是一种可以替代304奥氏体不锈钢的低镍不锈钢材料,以良好的经济性、力学性能和耐腐蚀性而被广泛研究,在核电工程中具有广泛的应用前景。针对核电工程水下维修技术背景,利用光学显微镜和电子背散射衍射等方法,研究了水下环境激光填丝直接能量沉积工艺制备的贫双相不锈钢2101的微观组织和织构演变。结果表明,水下环境对熔池的快速冷却作用抑制了铁素体向奥氏体的转变进程。由于铁素体的表面能最低,大多数铁素体是沿着密排堆积的(111)α和(110)α平面沉积的,沉积结构呈现典型的立方结构和高斯结构。尽管奥氏体的织构不如穿过沉积层的铁素体的织构强,但结果表明,奥氏体相相对于铁素体相形成了更紧密的Kurdjumov-Sachs取向关系。激光填丝直接能量沉积工艺的循环再加热效应不仅改变了贫双相不锈钢2101的组织和织构,还影响了晶粒尺寸和特殊晶界的比例。提高沉积结构中∑3晶界的含量和分布均匀性,有利于增强沉积层的耐蚀性。
