Rolling contact fatigue deformation mechanisms of nickel-rich nickel-titanium-hafnium alloys

Autor: Mills, Sean H., Dellacorte, Christopher, Noebe, Ronald D., Amin-Ahmadi, Behnam, Stebner, Aaron P.

The tribological performance and underlying deformation behavior of Ni55Ti45, Ni54Ti45Hf1 and Ni56Ti36Hf8 alloys were studied using rolling contact fatigue (RCF) testing and transmission electron microscopy (TEM). TEM results of the as-machined RCF r

Heat treatment - microstructure - hardness relationships of new nickel-rich nickel-titanium-hafnium alloys developed for tribological applications

Autor: Mills, Sean H., Dellacorte, Christopher, Noebe, Ronald D., Mills, Michael J., Stebner, Aaron P., Amin-Ahmadi, Behnam

The effects of various heat treatments on the microstructure and hardness of new Ni56Ti41Hf3 and Ni56Ti36Hf8 (atomic %) alloys were studied to evaluate the suitability of these materials for tribological applications. A solid-solution strengthening e

Physics-informed machine learning for composition-process-property alloy design: shape memory alloy demonstration

Autor: Liu, Sen, Kappes, Branden B., Amin-ahmadi, Behnam, Benafan, Othmane, Zhang, Xiaoli, Stebner, Aaron P.

Machine learning (ML) is shown to predict new alloys and their performances in a high dimensional, multiple-target-property design space that considers chemistry, multi-step processing routes, and characterization methodology variations. A physics-in
