Sintering shape distortions controlled by interface roughness in powder composites
Abstract
The co-sintering of laminar composites is modeled by means of finite element simulations. The densification of an alumina/ceria-stabilized tetragonal zirconia polycrystal bilayer is optimized by substituting the conventional flat interface morphology with a wavy contact surface. The presence of such roughness significantly decreases the undesired macroscopic distortions characterizing multi-material sintering. Various configurations of the wavy interface are numerically reconstructed. The introduction of rough interfaces generates beneficial stress redistribution and constraint relaxation effects, thus reducing the bending of the composite. The obtained results are in good agreement with previously conducted experiments and provide new guidelines to prevent flaw generation.
