已有许多报道指出 ,通过添加Ｗ元素可提高高Ｃｒ铁素体耐热钢蠕变强度 ,其原因是Ｍ2 3Ｃ6碳化物和Ｆｅ2 Ｗ莱维氏相 (ｌａｖｅｓ)有提高蠕变强度和错位组织稳定的效果。日本东北大学等单位研究了在不析出Ｆｅ2Ｗ莱维氏相的条件下进行蠕变试验 ,研究了添加Ｗ对蠕变强度和组织稳
It has been reported in many reports that the creep strength of high Cr ferritic heat-resistant steels can be increased by adding W elements due to the increased creep strength and dislocation stability of M2 3C6 carbides and Fe2W laves Effect. Japan’s Tohoku University and other units studied under the conditions of Levin’s Fe2W precipitation creep test was studied to add W on the creep strength and tissue stability
