有关残余伸长的机理曾有人作了研究。
The mechanism of residual elongation after relaxation of stress has also been studied.
结果表明:随着初始主应力方向角的增大,轴向残余变形由压缩状态的正值逐渐过渡到伸长状态的负值。
The results show that: with the initial principal stress direction angle increases, the axial residual deformation from the compression state gradually transits to the elongation.
锰含量提高并选取合适的淬火温度后,残余奥氏体含量及稳定性提高,抗拉强度显著提升的同时保持了较高的伸长率。
The content and stability of retained austenite is higher after more Mn is added, and also the strength is higher with preferable elongation when the appropriate quenching temperature is chose.
