Abstract

Dense, highly textured ZrB2 and ZrB2-MoSi2 ceramics were fabricated via a strong magnetic field alignment method followed by spark plasma sintering. Unlike with the previous studies, which only focused on the alignment of single-phase particles, both ZrB2 and MoSi 2, which exhibited a magnetic anisotropy, have been aligned in this study. The alignment of MoSi2 in the same direction of ZrB 2 enhanced the degree of orientation of ZrB2, decreased the grain size, but increased the aspect ratio of the platelet ZrB2 grains. The microstructure and anisotropic mechanical properties as well as the oxidation resistance in different directions were discussed.
