Het zou aardig zijn om elk van deze termen even kort in 1 zinnetje te beschrijven. Scheelt weer onnodig klikwerk.

Ik vond op het artikel en:Tempering (metallurgy) alvast het volgende lijstje, dat alleen nog efkes vertaald moet worden:

  • Strength: This is resistance to permanent deformation and breaking. Strength, in metallurgy, is still a rather vague term, so is usually divided into en:yield strength (strength beyond which deformation becomes permanent), en:tensile strength (the ultimate breaking strength), and en:shear strength (resistance to transverse, or cutting forces).
  • en:Toughness: Resistance to en:fracture, as measured by the en:Charpy test. Toughness often increases as strength decreases.
  • en:Hardness: Hardness is often used to describe strength or rigidity but, in metallurgy, the term is usually used to describe resistance to scratching or abrasion.
  • en:Brittleness: Brittleness describes a material's tendency to break before bending or deforming either elastically or plastically. Brittleness increases with decreased toughness, but is greatly affected by internal stresses as well.
  • Plasticity: The ability to mold, bend or deform in a manner that does not spontaneously return to its original shape. This is proportional to the en:ductility or en:malleability of the substance.
  • Elasticity: Also called flexibility, this is the ability to deform, bend, compress, or stretch and return to the original shape once the external stress is removed. Elasticity is related to the en:Young's modulus of the material.
  • en:Impact resistance: Usually synonymous with high-strength toughness, it is the ability resist shock-loading with minimal deformation.
  • en:Wear resistance: Usually synonymous with hardness, this is resistance to en:erosion, en:ablation, en:spalling, or en:galling.
  • en:Structural integrity: The ability to withstand a maximum-rated load while resisting fracture, resisting fatigue, and producing a minimal amount of flexing or deflection, to provide a maximum en:service life.
