爆炸成形是一种板材成形的新工艺,近年来发展很快。但是,这种方法利用的是爆炸时所产生的强大冲击力,成形过程中毛料所承受的压力大,载荷持续时间短,在有模成形时,高速运动的毛料,还会与模壁发生剧烈的碰撞。因此爆炸成形之后,金属的性能发生那些变化,便成为人们所迫切关心的问题,同时也是这种工艺进一步推广应用之前所必须明确的问题。然而迄今为止,这方面系统的工作还不多,而且其中还存在着 Explosion forming is a new sheet metal forming process, developed rapidly in recent years. However, this method utilizes the powerful impact generated during the explosion, the pressure on the wool during the forming process is large, and the load duration is short. When the mold is formed, the wool moving at a high speed will also violently violate the mold wall Collision. Therefore, after the explosion forming, those changes in the performance of the metal, it has become an urgent concern for people, but also to promote the application of this process must be clear before the issue. So far, however, systematic work has not been done in this area, and it still exists
