What is Nickel Superalloy with Crack Resistance about?
This document describes a method for improving the resistance of nickel-based superalloys to hydrogen embrittlement and crack propagation. The method involves (1) providing a gamma-prime strengthened nickel-based alloy with specific composition ranges, (2) solution heat treating the alloy, and (3) aging the alloy at a temperature between 1300-1400°F. This produces beneficial microstructural changes that improve resistance to crack initiation and propagation in environments where hydrogen embrittlement may o
