Malleable: For metal, or other material, ability to be hammered, or pressed, permanently out of shape without breaking.

Ductile: The ability for material to deform  its shape usually by stretching.

Tensile Strength: The ability for material to stretch without breaking, cracking, or snapping.]]> 2018-04-24 00:48:10 UTC https://padlet.com/skulls_pugs/fhaidji9jw46/wish/254646656 Hot Working skulls_pugs https://padlet.com/skulls_pugs/fhaidji9jw46/wish/254660877
  • Temperature above re-crystallization, so crystallization takes place
  • Ultimate tensile strength 
  • Corrosion resistance is unaffected
  • Material is uniform throughout
  • Less risk of cracks
  • Required less energy for plastic deformation since material is more ductile and soft

  • Temperature below re-crystallization so Crystallization does not take place
  • Increases ultimate tensile strength
  • Decreases resistance to corrosion.
  • Material is no uniform after
  • More Risk of cracks
  • Requires more energy for plastic deformation
