摘要
The paper focused on the effect of high-temperature sintering along with the back pressure equal channel angular pressing (ECAP-BP) on the porosity distribution in powder metallurgy (PM) aluminium alloys. Analyses of the dimensional and morphological parameters indicate that high-temperature sintering couples to ECAP-BP lead to porosity reduction and improve pore morphology. ECAP-BP influences the porosity distribution in terms of the severe shear deformation involved and therefore influenced the pore morphology along with pore distribution.
