摘要
采用焊接热模拟和断裂韧性COD技术,研究了拘束应力对15MnMoVNRE钢焊接热影响区(HAZ)的相交及COD的影响。结果表明,拘束应力促进了相变的进行并使断裂韧性提高。
The effects of restraint stress on phase transformation and fracture toughness COD in weld HAZ of 15MnMoVNRE steel were studied by means of weld thermal simulation and COD testing. The results show that restraint stress accelerates phase transformation and makes the fracture toughness COD higher.
