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:XCQ16钢具有较宽的回火温度范围。经860℃淬火的XCQ16钢在570℃回火时,其强韧性可以达到良好的匹配,为工业中车桥产品热处理制度的确定和优化提供了依据。
The effects of different tempering temperature on microstructure and mechanical properties of XCQ16 steel were studied. The experimental results show that XCQ16 steel has a wide tempering temperature range. After quenching at 860 ℃, XCQ16 steel tempering at 570 ℃, its toughness can achieve a good match for the industrial axles product heat treatment system to determine and optimize the basis.
