the ability of metal перекристаллизовываться at high temperature is used for hot processing. 2. recrystallization is the growth of new, free from deformation of grains. 3. during the hot processing of metal may be subjected to very large plastic deformation of compression. 4. cold processing makes the metal harder and stronger, but some metals have the limit deformation. 5. sheet metal may be hot or cold. 6. the surface холоднокатаного leaf more smooth and stable. 7. cross-section фильеры for extrusion can be simple or complex. 8. aluminum and copper alloys are the best for the extrusion of their plasticity during deformation. 9. aluminum cans, тюбики for toothpaste are examples of выдавливанием stamping. 10. the wall thickness of aluminum cans is determined by the gap between пунсоном and stamp.
