Abstract
A combined mechanical and thermal analysis of cold uniaxial powder compaction is presented where the analysis was coupled via friction and plastic work heating and the local density field. Experimental work confirmed that powder thermal conductivity increases rapidly with densification and that it is determined principally by the conductivity of the stock material. The numerical modelling work showed the dominant effect of frictional heat input with regard to temperature rise. The analysis also showed that compact temperature was also increased at higher compaction speed and that the effect of the interface heat transfer between the powder and tooling is important. PM/0778
