The influence of vacuum heat treatment and annealing on the structure and mechanical characteristics of a nickel-based superalloy

The authors studied the influence of vacuum heat treatment at 1210°C during 4 hr with subsequent annealing at temperatures from 950 to 1250°C during 5 hr on the structure and mechanical characteristics (ultimate strength, offset yield stress, relative elongation, percentage elongation at the maximum force, and percentage reduction of area) of a cast nickel-based superalloy ZhS-6U (mass%: 11.5 – 13.5 Cr ; 6 - 8 W ; 4 – 5.5Mo ; 4.7 – 5.2À l ; 2.2 – 2.8Ti ; < 2.0 Fe ; <0.4 Mn ; <0.4 Si ; 0.11 – 0.18 C ; 0.02 B).
