Heat treatments for high temperature cast aluminum alloys

Disclosed herein are embodiments of an aging heat treatment that can be used to replace conventional aging steps when making alloy embodiments of the present disclosure. Embodiments of the disclosed aging heat treatment reduce cost and complexity in producing aluminum alloy-based components while also promoting and/or improving microstructure stability of the aluminum alloys.
