AMES, Iowa – When Valery Levitas left Europe in 1999, he packed up a rotational diamond anvil cell and brought it to the United States. He and the researchers in his group are still using a ...

Martensitic phase transformations are rapid, diffusionless solid–solid transitions in which a parent crystal lattice reconfigures by coordinated shear and atomic shuffles into a martensite lattice.

High-pressure torsion (HPT) is a severe plastic deformation technique that imposes intense shear strain under quasi-hydrostatic pressures to refine grain structure and induce non-equilibrium phases in ...

The toughness, ductility, and wear resistance of metallic alloys are dictated by the phases present in their microstructure and how these phases are distributed. During heat treatments such as ...
