摘　　要：采用电子拉伸测试技术和图像分析技术(定量金相技术)研究了可膨胀管用低碳微合金化钢16MnMoVA在未经处理、经不同温度亚温淬火处理、经不同温度亚温淬火+高温回火处理后的组织性能。结果表明,16MnMoVA钢淬火成马氏体后,具有较大的残余应力;回火后,马氏体组织转变为回火索氏体,具备良好的性能;在预应变为3%,740℃和860℃的包申格效应最小。By electronic tensile experiment testing and image analysis （quantitative metallography ）, microstructure and properties of 16MnMoVA steel used as expansive tubes were investigated under untreated, different temperatures quenched, and different temperatures quenched add tempered. The results show that the steel martensite thransformation during quenching, causes a large residual stress. Martensite transforms to tempered sorbite after tempering, it has good properties. Bauschinger effect is minimum at 740 ℃ and 860 ℃ under pre-strain of 3%.
