| 摘 要： | 采用热模拟试验机、拉伸及冲击试验机和显微镜研究了热输入对06CuNiCrMoNb钢模拟焊接热影响区不同部位组织和性能的影响,重点分析了粗晶区的韧性与组织的关系.结果表明:模拟焊接热影响区没有出现"软化"现象,但当线能量＞30 kJ/cm时,粗晶区低温韧性迅速下降.

| Abstract: | The influence of the heat-input on microstructure and property in two regions of simulated welding heat-affected zone(HAZ) of 06CuNiCrMoNb steel were investigated,and the relationship between the toughness of the coarse grain heat-affected zone(CGHAZ) and microstructure were also discussed.The results show that the tensile strength of simulated HAZ dose not debase,but the low-temperature impact toughness of the CGHAZ declines rapidly on condition of heat-input above 30 kJ/cm. |
