Forming Single‐Phase Laminates via the Gelcasting Technique

Abstract

Single–phase laminates of iron titanate were formed by gelcasting in both the presence and absence of a magnetic field to produce alternating layers of textured and nontextured microstructure, respectively. X–ray analysis was performed on each lamina verifying that alignment was maintained throughout processing. Tunnel cracks were found in trilayer laminates (nontextured/textured/nontextured) when the alignment direction was parallel to the interface between layers. The cracks are consistent with a stress profile of residual tension parallel to the interface in the textured layer.
