摘要
采用示波冲击法研究了回火温度对P91钢动力强韧性的影响,通过分析P91钢示波冲击试验性能的差异及产生原因,并结合分析各试样的断口形貌,得出最佳回火温度为750～780℃.
The dynamic strength and toughness of P91 steel has been studied by means of the instrumented impact test with normalized P91 steel subjected to different temper temperatures. By contrast with the fractographic characteristic, the P91 steel property parameters of instrumented charpy impact test has been analysed. The optimized temper temperature is 750 - 780 ℃.
