HIGH TEMPERATURE FATIGUE CRACK GROWTH BEHAVIOR OF A NOVEL POWDER METALLURGY SUPERALLOY FGH98

测定了新型粉末高温合金FGH98在650℃空气环境中的疲劳裂纹扩展速率,与前两代粉末高温合金FGH95和FGH96的裂纹扩展速率进行了比较分析,研究了合金显微结构以及保载时间对FGH98合金裂纹扩展速率的影响.结果表明,FGH98合金的高温疲劳裂纹扩展抗力较前两代粉末高温合金有了明显提高.控制固溶后以适当的方式冷却,使得二次和三次γ′相均匀匹配析出,可以获得具有良好疲劳裂纹扩展抗力的合金组织.粗晶组织有利于降低FGH98合金的疲劳裂纹扩展速率,尤其是在近门槛区.FGH98合金的高温疲劳裂纹扩展速率随保载时间的增加而增加,其断裂模式相应地从穿晶-沿晶混合断裂变为沿晶断裂.
