“…Generally, the powder metallurgy processing causes the agglomeration in the case of ductile materials such as Cu and Al [13][14][15]. Further, the increased amount of alloying element and or severity of milling conditions leads to micro-porosity, brittleness of sintered samples and reduction in electrical conductivity of Cu materials [15][16][17][18][19][20][21][22][23][24].…”

“…Mixing of powders (less severe milling) at a lower milling speed can avoid such issues and improve the mechanical properties and electrical conductivity of Cu–Al with the advantage of low processing cost [24]. Song et al [16] studied the effect of milling and mixing of powders on densification and mechanical properties of WC-Co alloys. They reported that the sintered samples with the use of mixed powders showed better densification and ductility compared to milled powders.…”

In the present work, the effect of Al content (0, 3, 5, 10, 15 wt-%) on the microstructure, mechanical and wear properties of Cu was systematically studied. Interestingly, the coreshell microstructure was observed in the Cu-Al alloys or Al bronzes with different layers of α-Cu, and intermetallic phases. The Cu-Al alloys displayed good compressive yield strength of 174-653 MPa, in particular, the Cu samples with Al (upto 10 wt-%) did not show fracture upto strain of 40%. Abrasion wear was the predominant wear mechanism in pure Cu and Cu-Al alloys after sliding against SiC. The Al addition to Cu drastically decreased the wear rate (198 ×10 −3 to 3.8 ×10 −3 mm 3 N -1 m -1 ) of Cu-Al alloys. The present work demonstrates the advantage of the addition of (5-10 wt-%) Al to Cu in achieving good combination of mechanical and wear properties of Cu-Al alloys.
