Abstract
Target metal plates for PVD application made from ternary metal composites of Al, Ti* and Mg were produced by compacting metal powders. Al content was fixed at 70 wt. % and the other two were changed to study the effect of composition on the properties of the plates. Ti* powder, in the form of Ti6Al4V alloy, and pure Mg powder were varied in ratios of 2, 1 and 0.5 by weight. The compositions can be written as Al-70 wt.% Ti*-X wt.% and Mg-Y wt.% (X=20, 15,10, and Y=10, 15, 20). The powders were wet milled and compacted under uniaxial compressive load to form the plates. The strength of the plates was measured by performing 3-point bending tests and load till failure was reported. Effect of cold compaction load, mixing time of the powders and Ti* powder content on the microstructural and mechanical properties was studied.
