Effect of tempering process on the microstructure and mechanical properties of XCQ16 steel was investigated. The results show that XCQ16 steel present a wider tempering temperature range.

研究了不同回火温度对XCQ16钢微观组织和力学性能的影响，试验结果表明：xcq 16钢具有较宽的回火温度范围。

In addition, the temperature range of elastic abnormality will extend along with the increase in tempering time.

同时，随着回火时间增加，弹性反常的温度范围加宽。
