Various methods which might be used to reveal the voids in the steel were compared. Using a series of the interrupted smooth tensile specimens with an incremental plastic strain, the void nucleation was investigated in a C-Mn structural steel with lower sulphur content. 本文比较了各种可能揭示钢中空穴的方法,采用一系列具有增量塑性应变的光滑拉伸试棒调查C-Mn结构钢空穴的形核。
