Recrystallization occurs when Strain causes work hardness in

Recrystallization occurs when: Strain causes work hardness in metals. Metals are heated to above their recrystalization temperature Metals are cooled to below their recrystalization temperature, when alloying materials are added to a molten metal. Two types of metallic lattice structures are: Body-centered cubic & simple cubic. Face-centered cubic & covalent bonded, Hexagonal close-packed & Face centered cubic covalent bonded & ionic bonded.

Solution

Recrystallization occurs when stress causes work hardness in metals. deformation of grains and it is replaced by new grains occurs at the point recrystallization..Option a types of metallic structure are FCC ,HCP and BCC ,but above options contain FCC and HCP option 3 is ans
