1 Bulk deformation denotes large movement of material by deformation For example in hot rolling In hot working metals are worked well above the recrystallization temperature which makes the working on metals easier In commerical sense this process consumes less energy while deforming process And also handling hot metal is lot easier than coldworked material handling The term Bulk means final parts having relatively small surface area to voulme ratio 2 Four basic bulk See Answer
