Abstract

AZ31 magnesium alloy is used in different industries such as defence, aerospace, and biomedical applications, due to its high strength-to-weight ratio and it has a capability to expand its applications by improving its characteristics. Constrained groove Pressing (CGP) has a capability to produce ultrafine grained sheet (UFG) metals primarily based totally on severe plastic deformation, which can improve mechanical properties. Study on CGP of AZ31 magnesium alloy, which has poor formability and low ductility at room temperature (RT) is still difficult. The goal of this paper is to analysis the effects of constrained groove pressing (CGP) on the characteristics and applications of the AZ31 magnesium alloy at high temperatures. After the CGP process, most of the specimens mechanical properties like strength and hardness had improved. Microstructural changes and mechanical properties are also varying with the number of passes.
