摘要

Net-shaping capabilities of spark-plasma sintering are analyzed both theoretically and experimentally. The modeling includes the novel constitutive model of spark plasma sintering and the finite-element analysis with coupled electrical, thermal, and mechanical boundary conditions. Macroscopic modeling and experimentation are conducted for cylindrical and prismatic powder specimen shapes. The impact of the "shape factor" on the non-uniformity of electric current density, temperature, relative density, and grain size spatial distributions is analyzed. The modeling results are compared to the experimentally obtained data on the spark plasma sintering of ceramic (alumina) specimens of various shapes. The conducted research indicates the capabilities and addresses the challenges of spark-plasma sintering of complex-shape parts.
