利用改变炸药与取样部位间距离的办法,使初始组织结构和应力状态相同的16Mn钢焊缝受到强度不同的冲击波作用.研究了爆炸处理前后冲击波作用弹性区、塑性区、弹─塑性形变交界区16Mn钢焊缝的旋转弯曲度劳性能及铁素体内位错结构和形态,提出了爆炸冲击改善焊缝疲劳极限的位错缠结和钉扎理论.
In this research, welding joints of steel 16Mn in the same state of initial microstructure and residual stress were subjected to shock wave with different intensity by changing the distance between explosive and the sampling location of the specimen. The
