Aluminum alloys produced by powder metallurgy (PM) processing have the potential to solve many material problems in aerospace systems. However, to optimize fully the performance of these materials, strict processing control is required. For example, the breakup and redistribution of oxides, which is key to achievement of maximum properties, is directly related to vacuum degassing, hot pressing, and subsequent working of the material. An analysis of each of these steps is reviewed for aluminum PM Alloy 7091 with respect to oxide breakup and distribution.
