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。
In this paper, the ring-shaped flywheel cylinder contraction explosion method was used to study the high-temperature and high-pressure instantaneous (a few microseconds) of GF-3 high-speed steel powder under the action of shock wave to melt the particle surface and form the micro- So that the powder particles bonded together to achieve the purpose of sintering.
