Description
Summary:The effect of homogenizing isostatic treatment (HIT) of heat resistant nickel alloys on its phase composition and microstructure, and the consequent effect on its mechanical deformation are reviewed in the context of its use in aircraft components. The effect HIT of vacuum melted nickel alloys EP962 and EP741NP on microstructural homogeneity, eutectic composition, grain structure, recrystallization properties, and plasticity are covered. Effect of quenchant type on residual stresses is discussed.
