摘要
本文采用316L不锈钢和镍基高温合金进行了激光直接成形实验,系统研究了不同工艺参数对成形性能的影响规律;成形件内部组织致密,由生长方向不一的细长枝晶组成,并呈现出典型的外延生长特点;对成形过程熔池氧化对成形的影响进行了分析。
Laser direct forming experiments were carried out with 316L stainless steel and nickel - base alloy. The influences of processing parameters were investigated systematically. The microstructure of the components was dense and made up of fine dendrites, which grew epitaxilly. The influence of the oxidation in the melting pool was analyzed.
