The present disclosure concerns embodiments of aluminum alloy compositions exhibiting microstructural stability and strength at high temperatures. The disclosed aluminum alloy compositions comprise particular combinations of components that contribute the ability of the compositions to exhibit improved microstructural stability and hot tearing resistance as compared to conventional alloys. Also disclosed herein are embodiments of methods of making and using the alloys.

Rapid, reversible redox activity may be accomplished at significantly reduced temperatures, as low as about 200&#xb0; C., from epitaxially stabilized, oxygen vacancy ordered SrCoOand thermodynamically unfavorable perovskite SrCoO. The fast, low temperature redox activity in SrCoOmay be attributed to a small Gibbs free energy difference between the two topotactic phases. Epitaxially stabilized thin films of strontium cobaltite provide a catalyst adapted to rapidly transition between oxidation states at substantially low temperatures. Methods of transitioning a strontium cobaltite catalyst from a first oxidation state to a second oxidation state are described.
