Microstructure and Anisotropic Properties of Textured Zr B2 and Zr B2- Mo Si2 Ceramics Prepared by Strong Magnetic Field Alignment.

Dense, highly textured Zr B₂ and Zr B₂- Mo Si₂ 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 Zr B₂ and Mo Si₂, which exhibited a magnetic anisotropy, have been aligned in this study. The alignment of Mo Si₂ in the same direction of Zr B₂ enhanced the degree of orientation of Zr B₂, decreased the grain size, but increased the aspect ratio of the platelet Zr B₂ grains. The microstructure and anisotropic mechanical properties as well as the oxidation resistance in different directions were discussed. [ABSTRACT FROM AUTHOR]
