Based on a large number of experimental results, the reason why small-sized Goss grains can engulf surrounding large-sized grains and eventually grow abnormally was analyzed using the enhanced elastic ...

(a) Diagrams illustrating how columnar grains develop during the LPBF, contributing to microstructural anisotropy; (b) Stress-strain curves showing significant improvements in the mechanical ...
When materials are altered in shape by plastic deformation their grain shape tends to change. This is illustrated below for a wire being "drawn" into a dimension suitable for a bicycle spoke. While ...
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 ...
