摘　　要：研究固溶工艺对不锈钢车身加工成型性能的影响。研究表明,不锈钢固溶后硬度值受到奥氏体晶粒尺寸与固溶强化效果的共同影响,且显著小于冷轧态,表现出良好的加工成型性能。随着固溶温度的增加,硬度值有升高的趋势。随着保温时间的增加,材料具有更高的屈服点和更强的抵抗塑性变形的能力。In this paper,the effect of solution technology on the formability of stainless steel body is investigated.The results show that the hardness of stainless steel after solution is affected by austenite grain size and solution strengthening effect,and is significantly less than that of cold rolling,showing good formability.With the increase of solution temperature,the hardness value tends to increase.As the holding time increases,the material exhibits a higher yield point and a stronger resistance to plastic deformation.
