Simultaneous grain boundary motion, grain rotation, and sliding in a tricrystal [PDF]
Mechanics of Materials, 2015 Grain rotation and grain boundary (GB) sliding are two important mechanisms for grain coarsening and plastic deformation in nanocrystalline materials. They are in general coupled with GB migration and the resulting dynamics, driven by capillary and external stress, is significantly affected by the presence of junctions.

Using High-Pressure Torsion to Achieve Superplasticity in an AZ91 Magnesium Alloy
Metals, 2020 An AZ91 magnesium alloy (Mg-9%, Al-1% Zn) was processed by high-pressure torsion (HPT) after solution-heat treatment. Tensile tests were carried out at 423, 523, and 623 K in the strain rate range of 10−5−10−1 s−1 to evaluate the occurrence of ...
