| Abstract Scope |
Acceleration of sintering is a long-held engineering goal with significant payback in terms of higher production rates and lower energy costs. While it is common to optimize thermal cycles, powder characteristics, and additives to minimize sintering cycles, there is a large frontier opportunity to design new alloys for their ability to rapidly densify at low temperatures. In alloys that are designed to reversibly decompose and then resolutionize upon heating, a substantial amount of mass transport is triggered chemically; in a powder compact this transport is biased to eliminate surface area and can lead to rapid densification at temperatures that are tunable by alloy thermodynamics. A range of binary and multinary alloys that exhibit this phenomenon will be overviewed, with an eye towards the system thermodynamics and mass transport kinetics that regulate the process, as well as the extension of the concept to component manufacturing by 3D green body printing. |
