Introduction Materials with body-centred cubic (b.c.c.) structure is generally hard to deform at low temperatures, which leads to a brittle fracture while they become easy to deform plastically with increasing temperature, resulting in ductile failure.
The primitive dislocation glide process of silicon crystals is the same as that in b.c.c. materials because of their high values of Peierls potential.
