K438G is a modified K438 heat resistant corrosion cast nickel base alloy. It is characterized by low phosphorus content and small solidification segregation.……
Inconel 718 or In718 is a nickel-chromium-molybdenum alloy. It is an oxidation-resistant and corrosion-resistant material ideal for use in extreme environments under pressure and heat.……
The creep rupture strength can be a good indication that the creep rupture life/γ-initial fraction diagram of each alloy series is different, but each series may have a maximum value or exceed 75% (volume) in the vicinity.……
