Explain in detail how, in a polycrystalline metal, slip can be
transmitted from
one grain to a neighbouring grain. What governs the difficulty
involved in such
a slip transmission process? Hence, state and explain the grain
size dependence
of strength as given by the Hall-Petch relation. How does the grain
size
dependence of strength differ between BCC, HCP and FCC
metals?
