Selective-melt sintering is faster and more efficient than the methods currently used to make high-density ceramics. This article explains how applied electric fields contribute to the formation of metallic precipitates at grain boundaries and how defect segregation and field-assisted migration generate heat near dislocations and in grain boundaries, reducing flow stress and retarding grain growth in the solid state.
