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。 The electronic tensile test technique and image analysis technique (quantitative metallographic technique) were used to investigate the properties of 16MnMoVA low-carbon microalloyed steels for inflatable tubes. After untreated, sub-tempered quenching at different temperatures, Organizational performance after fire treatment. The results show that the quenched martensitic steel has great residual stress after being quenched into martensite. After tempering, the martensite transformed into tempered sorbite and has good properties. When the pre-strain is 3%, 740 ℃ and 860 ℃ Bauschinger effect of the smallest.
