摘要: 10Ni5CrMoV钢属于低合金高强钢,固态相变效应在其焊接热-力耦合分析中不可忽略.固态相变效应表现为体积变化和屈服强度"滞后"现象,通过热膨胀试验测试相变参数,建立固态相变的数学模型,开展了考虑固态相变效应的10Ni5CrMoV钢焊接热-力耦合分析.结果表明,考虑固态相变效应后,焊缝及焊缝附近(相变区域)纵向拉应力大幅度降低,相变区域相邻位置拉应力仍然较高;横向应力的分布状态变化明显,应力峰值变化较小,约为室温屈服强度的25%.应力测试结果与数值模拟结果较吻合,验证了固态相变模型的准确性.

Abstract: 10Ni5CrMoV steel is a high strength low alloy steel (HSLA), its solid-state phase transformation effects cannot be ignored in welding mechanical analysis. In this study, welding numerical simulation is conducted with consideration of solid-state phase transformation effects including volumetric change and hysteresis of yield strength. The results show that longitudinal tensile stress become much lower in phase transformation zone, but it maintains high stress level in adjacent areas. Nevertheless, the distribution of transverse stress is changed a lot, with a similar peak value, approximately 25% of yield strength at room temperature. And it is approved that both longitudinal and transverse residual stress are in good agreement with experimental measurements. -
