摘　　要：介绍了铁、镍基合金等的无接触电磁约束成形定向凝固技术。在系统研究电磁场与温度场及其耦合作用的基础上,成功地实现了对多种截面形状的铝、不镑钢及高温合金的无容器电磁约束成形。In this paper,recent research on electromagnetic shaping and directional solidification of Fe- and Ni-base alloys is introduced. Based on a systematic investigation on the distribution behavior of magnetic and temperature field and their coupling effect,some different cross-section samples of aluminum,stainless steel and superalloy were successfully obtained.
