中文摘要：
运用Gleeble-1500热模拟试验机对254SMO奥氏体不锈钢进行了高温拉伸试验,利用光学显微镜、扫描电镜等对热模拟拉伸断口进行了表面形貌观察。结果表明：254SMO奥氏体不锈钢热塑性的优劣主要由脆性的σ析出相决定;热模拟时各温度段的断裂微观机制均不同,254SMO奥氏体不锈钢最适宜的热塑性温度宜选在1200℃临近区域。
英文摘要：
The fracture toughness of 254SMO austenitic stainless steel was studied by Gleeble-1500 thermal simulation testing machine.The fracture surface and microstructure of 254SMo austenitic stainless steel were analyzed at thermal simulation temperature by SEM,ESA and XRD.The research results show that the thermo-plastic quality of 254SMO austenitic stainless steel is mainly caused by the precipitates σ phase.The fracture mechanism at temperature period in thermal simulation is different.The optimum thermo-plastic temperature of 254SMO austenitic stainless steel is nearly 1200 ℃.
