摘要: Microstructural processes of the formation grain boundary cavities during deformation an A1-4.5 mass% Mg solid solution alloy at high temperatures (373-623 K) were discussed from a viewpoint microstructure. Structural examination was carried out mostly 533 K which, under strain rate 2.7×10 -5 s -1 , ductility (the reduction in area fracture) took minimum value (-48%) and mode fracture intergranular because severe cavitation
