Twins boron carbides

Figure 43. Hot-pressed B-doped boron carbide with strain-induced polysynthetic twinning.

Figure 72. DIG, Sintered and isostatically hot-pressed boron carbide after etching. Shows coarse and fine grains, twinning, and pores.

Figure 83. Pressureless-sintered silicon carbide doped with boron carbide, BF. Etched by the Murakami method. Shown here are pores and elongated SiC grains and twins.
