Describe the Uses of Hot Working and Cold Working
Hot working and cold working are metallurgical processes used to obtain desired properties in metals. Hot working is most preferred where heavy deformation is required. Hot And Cold Sort Objects And Clothing Preschool Prek Kindergarten Weather Activities Preschool Winter Activities Preschool Preschool Weather During hot working as the metal is in a plastic state larger deformation can be accomplished and more rapidly. . Refinement of grain occur Porosity of ingot is eliminated Uniformity and directional property is improved Toughness ductility elongation reduction in area are improved Power required is less Rapid and economical process Cons. The key difference between hot working and cold working is that hot working is done at temperatures above recrystallization temperature of the metal whereas cold working is done at temperatures below the recrystallization temperature of the metal. Hot working is usually performed at elevated temperatur...
