摘要
对AI-0.35Sc合金中加入同含量的微量过渡族元素Zr、Ti,采用正交实验测定了这些含Zr、Ti元素的AI-Sc合金的高温(270℃)持久寿命,并应用扫描电镜,观察了断口形貌,分析断裂机理。
Adding different amount transition elements Zr. Ti to the Al-0.35Sc alloy, orthogonal design isused to measure high-temperature dulation life of the alloys containing Zr.Ti elements at 270℃ 60 MPa.Fracture morphology is observed by means of SEM, fracture mechanism is analysed.
