Mechamism of Grain Refinement in Al after COT Deformation

Abstract:

The microstructure of Al processed by compression with oscillatory torsion (COT) method have been studied. This method was applied to refine the grain structure to ultrafine dimension. The aim of the study was to examine how severe plastic deformation technique (COT) - alter the microstructure. The second aim is to understand the mechanism of grain refinement. The microstructure was characterized using transmission electron microscopy (TEM) and scanning electron microscopy (SEM) equipped with electron back scattered diffraction (EBSD) facility.
