| Abstract Scope |
Materials processed utilizing high-pressure torsion can contain a heterogeneous or hybrid microstructure and hierarchical nanostructure. This complex microstructure was induced into multi-phase refractory compositionally complex alloys utilizing high-pressure torsion for processing by applying a pressure of 6 GPa for a variable of turns to discs that are 10 mm in diameter and approximately 0.9 mm in thickness. The microstructural evolution and mechanical behavior of the processed material is investigated using x-ray diffraction, energy dispersive x-ray spectroscopy, nanoindentation, and complementary techniques. Analysis of this data will provide insight into new material compositions of interest for further investigation of unique properties and applications. |
