Powder processing can allow for customization of alloys and precise shape control with very little waste. Currently accepted technologies like HIPing and spark plasma sintering are expensive and time-consuming. Resistance sintering of powder for consolidation is an advancement on those technologies allowing for faster processing with associated cost reduction. Previously EWI has demonstrated the ability to use resistance sintering to produce consolidated Ti billets with extremely high density. This process has been modeled previously by treating particle to particle contacts during sintering as a series of projection welds that result in consolidation. This work expands on that model to focus on the localized heating within the billets and mapping out the solid-state bonding physics of the puck during the entire weld cycle.
