Computational Tools for Assurance of High-Strength, Fatigue-Resistant Aluminum Castings

ABSTRACT
Microporosity and oxide films along with eutectic and precipitate structure in case aluminum allows are major detriments to the fatigue resistance of aluminum castings. Optimizing heat treatment using kinetic modeling and simulation together with thermodynamic and thermophysical information can minimize residual stress and distortion while maximizing resistance to crack propagation and fracture.
