Work Hardening and Annealing of Copper

This experiment demonstrates the process of work hardening in a copper,that is,hardening the metal by deformation.If an appropriate furnace is available,it also demonstrates the softening process of annealing.Copper wire or tubing is quite soft in its initial state,allowing for a variety of uses where the tubing needs to be bent to a desiredWhat is the effect of repeating annealing process on the In principle,annealing of metallic alloys involves a number of diffusion governed processes having additive character.So,through applying it twice (or more times),the overall effect will be What is Annealing? Heat Treatment of Steels - Annealing Process Annealing - This process is mainly suited for low carbon steel.The material is heated up to a temperature just below the lower critical temperature of steel.Cold worked steel normally tends to posses increased hardness and decrease ductility making it difficult to work.Process annealing tends to improve these characteristics.
