摘要：
Results are given for a study of the effect of quenching temperature on macro- and microstructure, and mechanical properties of nickel-based superalloy EI437B-VD. It is shown that in order to improve structure stability and mechanical properties of rolled bar and stamped GTE blades made of alloy EI437B-VD, and also to avoid a different grain size, it is necessary to reduce quenching temperature in performing heat treatment from 1080 ± 5°C to 1020 ± 5°C.
