PWA 1426

1. Introduce – A nickel-based superalloy designed for use in high-end military and commercial turbine airfoils – A second-generation dendritic (DS) alloy with high-temperature strength comparable to that of single-crystal (SC) nickel-based alloys – Improved mechanical properties (creep rupture strength, thermal fatigue strength) and oxidation resistance compared to existing dendritic alloys (PWA 1422) * PWA Alloy √ An alloy primarily used for airfoil compressor blades in turbine engine fans * Columnar Grain √ Long, thin grain structures formed during solidification when there...
