The Effect of Type of Cold-Deformation on the Recrystallization Properties of Armco Iron
The recrystallization of Armco iron when cold deformed by torsion, elongation in tension, nd rolling, and subsequently annealed, has been studied with care taken to keep variables other then the type of deformation as alike as possible. From the data in each case a recrystallization diagrams was constructed. It was found possible to replace the critical degree of deformation at any chosen annealing temperature for the three different types of cold deformation by expressing the degree of deformation either in terms of specific shear or better (following Nadai), in terms of octahedral shear. Experiments on the effect of time of anneal were also carried out.
