| 摘 要： | 本文采用环状飞片柱面收缩爆炸方法,研究了GF_3高速钢粉末在冲击波作用下,瞬时(几微秒)产生高温高压,使颗粒表面熔化,在随后激冷凝固过程中形成微晶组织,使粉末颗粒相互粘结在一起,达到烧结的目的。

| Abstract: | In this paper, the sintering mechanism of GF3 high-speed steel powders has been investigated by means of a cylinderically converging explosive method with a ring-shaped flyer.It has been shown that shock waves produce high temperature and high pressure in a few microseconds, which leads to that melting occurs at the interface of the metallic powders and caructure causes inter-particle welding resultion in microcrystaline structure and sintering of powder particles in the rapid solidifying process followed. |
