摘要
镍基单晶高温合金是高推重比发动机涡轮叶片的关键材料。综述了镍基单晶高温合金的反常屈服行为,并讨论了导致产生这种反常屈服行为的变形机制及这些变形机制的发展过程。
Nickel base single crystal superalloy is a key material blade for turbine engine blade having high thrust-weight ratio. A comprehensive description is given to the abnormal yield stress of nickel base single crystal superalloy. Meanwhile, the deformation mechanism of nickel base single crystal superalloy is discussed.
