The excellent cryogenic tensile properties of the CrMnFeCoNi alloy are generally caused by deformation twinning, which is difficult to achieve at room temperature because of insufficient stress for ...

(a) Diagrams illustrating how columnar grains develop during the LPBF, contributing to microstructural anisotropy; (b) Stress-strain curves showing significant improvements in the mechanical ...

Researchers determined exactly what happens as crystal grains in metals form during an extreme deformation process, at the tiniest scales, down to a few nanometers across. The findings could lead to ...

How the tiny crystalline grains that make up most solid metals actually form. (Courtesy: Christopher Schuh, Keith Nelson, and James LeBeau) When steel, aluminium and other widely used metals or alloys ...
