Effect Of Equal Channel Angular Pressing On The Microstructure And Mechanical Properties Of A356 Alloy

This work investigated the effect of equal channel angular pressing (ECAP)on the microstructure and mechanical properties of non-dendritic A356 alloy.This alloy was casted by cooling slope casting in order to produce a globular microstructure feedstock for ECAP process.After that,ECAP process was pe...
