Under mechanical loading, nanocrystalline metals show unique behaviour, among the most common of which are high strength, mechanically induced grain growth and twin formation. However, mechanically ...

Researchers at the University of California, Irvine and other international institutions have for the first time achieved atomic-scale observations of grain rotation in polycrystalline materials.

This work sets forth the first thermodynamically consistent constitutive theory for ice sheets undergoing strain-induced anisotropy, polygonization and recrystallization effects. It is based on the ...
