Investigation on die wear behaviour during compaction of aluminium matrix composite powders

Abstract

The focus of the current study was to evaluate and quantify the effects of particle reinforcements and lubricants on the die wear during compaction of Al matrix composites. A new wear model was developed and combined with experiments to quantify die wear using automatic die compaction experiments. The influences of the reinforcement particle type and content, as well as the premixed lubricant content, are presented and discussed.
