研究了１６ＭｎＵ型钢亚温淬火后的形变强化性能，结果表明：１６ＭｎＵ型钢经８２０℃×３０ｍｉｎ水淬＋２００℃回火后，具有较好的形变强化性能，适合于工程应用．影响其形变强化性能的主要因素为淬火加热温度，其次是钢中的碳、锰含量及回火情况．
The deformation strengthening of 16MnU steel after subcritical quenching was studied. The results show that the 16MnU steel has good deformation strengthening properties after tempered at 820 ℃ for 30 min and tempered at 200 ℃, which is suitable for engineering application. The main factors affecting the deformation strengthening performance are quenching temperature, followed by the carbon and manganese content in steel and tempering.
