Annealing to Increase Metal Ductility - Industrial Metallurgists

Process annealing, also called intermediate annealing, subcritical annealing, or in-process annealing, is a heat treatment cycle that restores some of the ductility to a product being cold-worked so it can be cold-worked further without breaking. The temperature range for process annealing ranges from 260 °C (500 … See more In metallurgy and materials science, annealing is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness, making it more workable. It … See more Annealing occurs by the diffusion of atoms within a solid material, so that the material progresses towards its equilibrium state.
