Definitions. OL question 2 and 3

Define Hardness A material with good resistance to scratching and wear.
Define Toughness A material with good resistance to impact and will not crack
Describe Brittleness A material that is very hard and will fail by cracking easily.
Define ductility A material which can be easily drawn into wire by making it thinner and longer
Define malleability A material that is easily stretched and shaped. This can be made easier by heating
Describe Work Hardening A material loses its ductility when bent or hit with a hammer and causes to become harder and more brittle
Describe Elasticity A material that can be stretched but will go back to its original length
What is an insulator A material that is a poor conductor of heat and electricity e.g PVC or Rubber coating on an electrical cable.
What is a conductor A material that will allow heat and electricity to pass through it easily
Explain the term 'Melting point' The temperature that a metal will start to turn from liquid to solid.
Describe plasticity A material that will not tear when deformed.
Explain Creep (HL ques) Failure of a metal which is under a constant load. It is subjected to tension causing elongation and fracture leading to failure. The rate of creep can speed up if the temperature of the metal increases
Explain Fatigue. Failure of a metal which is under a fluctuating load which leads to cracking and failure. Poor design can lead to fatigue failure.
