Tailoring Plate-Like Grained ZrB2 Ceramic via a Strong Magnetic Field Alignment Method Followed by Spark Plasma Sintering

Article Preview

Abstract:

Through strong magnetic field alignment (SMFA) method followed by spark plasma sintering (SPS), dense tailored ZrB2 ceramic could be prepared using the plate-like grains as initial material. The measured Lotgering orientation factor f(00l) on the textured top surface (TTS) was high as 0.62 and f(hk0) on the textured side surface (TSS) was 0.65. Vickers hardness measurement showed the anisotropic mechanical property of textured sample. On the TTS, the hardness was 13.4 ± 0.9 GPa, while on the TSS the hardness was 12.0 ± 0.9 GPa.
