“…Al-Cu alloys are generally strengthened by θ (Al 2 Cu) precipitates [10,11], and the addition of Mg enhances diffusibility and improves sintered properties of Al P/M alloys by destroying Al 2 O 3 layers on Al powder surface forming MgAl 2 O 4 spinel structure [12].…”

The objective of the present research is to develop a novel lubricant for Al-Cu-Mg P/M alloy and to address the effects of the lubricant and compaction pressure on sintered properties. A lubricant mixture consisting of Ethylene Bis Stearamide, Zn-Stearate, and fatty acid was newly developed in this study, and the de-lubrication behavior was compared with that of other commercial lubricants, such as Ethylene Bis Stearamide, Zn-Stearate, and Al-Stearate. Density and transverse rupture strength of sintered materials with each lubricant were examined, respectively. The microstructural analysis was conducted using optical microscope.

In the present study, pure magnesium was in situ coated with pre-alloyed Al-Cu-Mg alloy through hot pressing. The produced samples were characterized by means of hardness, wear properties and microstructure characterization. A ball-on-disk test was used to determine the dry sliding wear characteristics of the compacts. The results showed that the hot pressing technique has been successfully applied for producing magnesium parts with compatible wear resistance and hardness to aluminum. The in situ coating of Al on Mg by hot pressing resulted in an increase in hardness of about 30% compared with the pure Mg substrate. The wear rate and friction coefficient of the samples decreased with Al coating and increased with an increase in the applied load during the wear tests, compared with the uncoated material.

“…Powder metallurgy can increase the material utilization, which is an ideal process to fabricate high performance and low cost materials [1][2][3][4][5][6] .The copper and copper alloy products prepared by powder metallurgy have good thermal conductivity, high corrosion resistance and good surface finish, and they are nonmagnetic. Due to these favourable atrributes, powder metallurgy copper and copper alloy products are widely used in automotive, appliance, electronics, communication and other areas, and thus play an important role in industrial production [7][8][9][10][11][12] .…”
