- Both the rupture life and elongation of as-cast M963 superalloy under 1923 K melt superheating treatment and 1248 K/225 MPa can be doubled and even more.
在1923 K温度下进行熔体过热处理;可使M963合金在1248 K/225 MPa条件下的持久寿命和持久塑性同时提高一倍以上.
- The crystallographic constitutive models for the plastic and the creep behaviors and the method of the rupture life prediction were established and verified.
- As RE is beyond 0.1wt.%, creep rupture life decreases, especially when RE adds up to 1.0wt.%, the lifetime of SnAgCuRE solder joint is below that of Sn-3.8Ag-0.7Cu, but is similar to Sn-37Pb.
