The paper deals with the compressibility analysis of PM aluminium alloys Al-Mg-Si-Cu-Fe and Al-Zn-Mg-Cu-Sn. Compaction pressures ranged from 50 MPa up to 700 MPa.

Abstract

The paper deals with the compressibility analysis of PM aluminium alloys Al-Mg-Si-Cu-Fe and Al-Zn-Mg-Cu-Sn. Compaction pressures ranged from 50 MPa up to 700 MPa. Considering the densification of metal powders in uniaxial compaction, quantification of aluminium compaction behaviour was performed using the linear regression analysis. The compressibility behaviour was evaluated in relation to geometry and mechanical properties of powder particles on pressing pressure as well as microhardness values. The development of compressibility values with pressing pressure enables to characterize the effect of particles geometry and matrix plasticity on the compaction process.
