A steel alloy with unique and superior combinations of properties such as elevated temperature strength, oxidation resistance, thermal conductivity and wear resistance. Disclosed embodiments comprise or substantially consist of: C in an amount of 0.2-0.45 weight %; Si in an amount of 0.6-1.1 weight %; Mn in an amount of ≤1.1 weight %; Cr in an amount of 2.5-4.0 weight %; one or both of Mo or W, a combined amount of the Mo or W≤0.9 weight %; Ti in an amount of 0.035-0.14 weight %; V in an amount of 0.18-1.1 weight % and the balance being Fe and usual impurities.

Steel alloy and method of manufacture exhibiting enhanced combination of high temperature strength, oxidation resistance, and thermal conductivity

The present disclosure concerns embodiments of aluminum alloy compositions exhibiting superior microstructural stability and strength at high temperatures. The disclosed aluminum alloy compositions comprise particular combinations of components that contribute the ability of the alloys 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.

Aluminum alloy compositions and methods of making and using the same

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.

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.
