摘 要: 進行了退火對鈦-鋼爆炸復合板中飛線(絕熱剪切線)組織影響的試驗。發(fā)現(xiàn)在一定工藝下退火后這種飛線會自行消失，而由飛線發(fā)展成的裂紋則不會。由此論證了飛線是一種塑性變形組織和裂紋源。這種飛線可能還是爆炸載荷下金屬中出現(xiàn)的一種新的和特殊的塑性變形機制。

Abstract:The effect of annealing on fly line structure and properties in titamium-steel explosive composite sheet was investigated. The results show that the fly line will disappear after annealing, which demonstrates that the fly line is a kind of plastic deformation structure and crack source. This kind of fly line may also be a sort of new deformation form at explosive load in metal.
