Hot ductility and surface cracking of low carbon low alloy steel
低碳低合金钢的热延性及表面裂纹
The area of inductile, namely crack-sensitive spot, is found by the curve of hot ductility temperature and cross section shrinkage ratio.
通过绘制变形温度与断面收缩率的关系曲线,找出了该钢的低塑性温度区,即裂纹敏感点。
The reduction of ductility of K17 alloy after post hot-isostatic pressing ( HIP) heat treatment, which increases the high temperature rupture and the tensile properties of the alloy, was investigated in this paper.
K17合金在热等静压后进行再热处理,能提高合金的高温持久与抗拉性能,但其塑性明显下降。
