爆炸焊接外复法制取铌-不锈钢复合棒

Producing Nb-stainless steel clad rods by outer-clad explosive welding method

采用爆炸焊接中的外复法,并控制爆炸能量,使3.8mm的不锈钢管与铌棒在固态下产生高强度的冶金结合,其性能超过了预定的技术指标。若炸药的品种、药量、间隙等影响爆炸复合的主要工艺参数选择得当,动态条件合适,其最高结合强度可以达到铌材的强度,产生等强结合。

The metallurgical bond between the Nb and the stainless steel was obtained under the appropriate dynamic conditions, and the predestinated technical requirements can be reached. Furthermore, a maximal bonding strength equal to that of the Nb rods can be achieved under due conditions. The so-called equal strength would be resulted if parameters, such as the type and the amount of the explosive, the gap between the prepared raw materials, are properly chosen and the dynamic conditions are suitable.
