摘要
采用冲击试验机、X射线应力检测仪、光学显微镜(OM)和扫描电子显微镜(SEM)等仪器观察和分析了2Cr13不锈钢在920 ℃~970 ℃温度下淬火、700 ℃回火与激光冲击(LSP)复合处理后的冲击韧性、残余应力、金相组织和断口形貌。结果表明,随着淬火温度的升高,2Cr13钢的冲击韧性为先增加后减少;尤其是在淬火温度为940 ℃、回火700 ℃热处理后,LSP强化得到的冲击韧性最高。在这种条件下,其残余压应力相比其他热处理的残余应力要稍高,冲击断口断裂为准解理与韧窝的混合型断裂。
Abstract
The impact toughness, residual stress, metallographic organization and fracture morphology of 2Cr13 steel quenched temperature at 920 ℃~970 ℃, tempering at 700 ℃ and laser shock processing (LSP) are investigated by means of impact testing machine, X-ray diffraction, optical microscopy (OM), scanning electron microscopy (SEM). The experimental results demonstrate that the impact toughness of 2Cr13 steel increases firstly, but decreases afterwards as the temperature of quenching rises, particularly, the impact toughness of 2Cr13 steel reaches the peak in the quenching temperature at 940 ℃, tempering at 700 ℃ and LSP. Under this condition, the residual stress is a little higher than that of the other heat treatment,and the impact fracture of 2Cr13 steel is quasi-cleavage and dimple.
