Presentation Transcript
brittleness
Brittleness
  • A property of a metal that does not allow movement of material or distortion before it will break.
tensile strength
Tensile Strength
  • A measurement of how much a metal can stretch before breaking or failing.
toughness
Toughness
  • A property required for many tools, as it allows materials to withstand impacts without breaking or chipping.
hardness
Hardness
  • A material’s resistance to permanent deformation after facing a force exerted by another object.
malleability
Malleability
  • A property that allows materials to be continuously reshaped and formed without breaking.
ductility
Ductility
  • A property that allows materials to be easily formed after experiencing a force via another object.
elasticity
Elasticity
  • A material’s ability to return to its original shape after a force acting upon it has been removed.
hardening
Hardening
  • A process in which metals increase their resistance to penetration by an object imposing a force upon them.
  • Hardening can be achieved by cold working or most commonly by heating a material by various means to a given temperature and rapidly cooling it to form a finer internal grain structure.
tempering
Tempering
  • A process of heat treating, which is used to increase the toughness of iron-based alloys.
  • Tempering is usually performed after hardening, to reduce some of the excess hardness, and is done by heating the metal to a much lower temperature than was used for hardening.
  • The exact temperature determines the amount of hardness removed, and depends on both the specific composition of the alloy and on the desired properties in the finished product
annealing
Annealing
  • A heat treatment wherein a material is altered, causing changes in its properties such as hardness and ductility
  • Annealing is used to induce ductility, soften material, relieve internal stresses, refine the structure by making it homogeneous and improve cold working properties.
annealing cont d normalizing
Annealing Cont’d….(Normalizing)
  • An annealing process in which a metal is cooled in air after heating in order to relieve stress.
  • It is used to refine grains which have been deformed through cold work, and can improve ductility and toughness of the steel.
