为了研究Ta含量对低碳还原活化铁素体/马氏体钢高温力学性能的影响，制备了不同Ta含量(0.073%和100%)的低碳还原活化铁素体/马氏体钢，进行了室温和高温拉伸试验，并在550℃、180和220℃下进行了蠕变试验。结果表明，0.073%的Ta使钢中稳定的碳氮化物(MX)含量增加，钢在180℃下的蠕变断裂时间明显延长。此外，添加Ta引起的Mx的增加也导致高温拉伸强度的提高。RAFM钢高温力学性能的改善主要与析出相的演化有关。
To investigate the influence of tantalum content on high-temperature mechanical properties of low-carbon reduced activation ferritic/martensitic (RAFM) steels, RAFM steels containing different tantalum contents (0 and 0.073%) were fabricated, and the tensile tests at room temperature and high temperature were performed, as well as the creep tests were conducted at 550 °C with the applied stress of 180 and 220 MPa. It was found that 0.073% tantalum addition results in the increase in amount of stable carbonitrides (MX), and the creep rupture time of the steel under 180 MPa is obviously increased. In addition, the increase in MX caused by tantalum addition also leads to the improvement of high-temperature tensile strength. The improvement of high-temperature mechanical properties of RAFM steels is primarily related to the evolution of precipitates.
