摘要
对A3钢-黄铜爆炸焊接的结合机理进行了深入的探讨.利用金相显微镜、电镜扫描、电镜透射等检测手段对爆炸焊接结合界面的微观结构进行了分析,并对爆炸焊接结合界面进行讨论.不同金属在高速碰撞产生的高压、高温、强烈的塑性变形和扩散中,将发生熔解和化合,生成一些不同于基体金属的新的组成物结合区的组织.金属的爆炸焊接综合了熔化焊、压力焊、扩散焊以及射流4个方面的特点,是一个比较复杂的过程.
The bonding mechanism of explosive welding is studied. On the basis of explosive welding experiments of brass and A3 steel, the bonding boundary microstructure is made by means of microscopic examination, electron microscope scanning and transmission. The bonding zone texture is also explored. It is concluded that the two materials melt and compound during high pressure, high temperature, intense plastic deformation and diffusion which are caused by highspeed collision. Therefore, the resulted bonding zone texture is different from the original metals. The explosive welding of metal includes the characteristic of melting welding, pressure welding and diffusion welding. it is a complex process.
