When material is hardened by torsional prestrain in engineering, the multitude of prestrain should be as high as possible and at the same time microcracks on the surface of specimen should be avoided, in order to get a.
研究了经过预扭转变形强化后某低合金钢在拉伸中的强塑性变化规律,并对该工艺的强化效果和其对材料塑性潜力的发挥给出了定量分析,在此基础上讨论了材料强塑性的合理配合。
