Deformation features of the boron carbide lattice treated in a planetary ball mill are studied in our work. It is shown that such treatment causes a decrease in the B 4 C grain size and cracking along the {20 2 ¯ 1} h planes, whereas the same treatment in the presence of silicon results in the appearance of twins along the {10 1 ¯ 1} h planes. Distorted stacking faults along …
