Defects in the Heat Treatment of Steel | Metals | Industries | Metallurgy
Principal defects in steel due to heat treatment and measures for their elimination: Defect # 1. Overheating: Coarse grained micro- structure and fracture. Reduced ductility and specially reduced impact strength Causes: Heating for longer periods at temperatures considerably above the normal values. Prevention: i. For slight overheating, use normal annealing and normalising. ii. For considerable overheating, use double annealing or [...]
