| 内容記述 | Changes in the microfissuring susceptibility of alloy 718 due to solution annealing and age hardening are studied. The effects of Ni3Nb (delta) precipitation during solution annealing and gamma-prime + gamma-double-prime precipitation during age hardening on microfissuring are investigated. It is observed that solution annealing reduces microfissuring and age hardening increases it, and the two precipitates do not affect microfissuring susceptibility. Potential causes for the detected intergranular segregation of the alloy are discussed. |
