1. Why are components made from steel or aluminum alloy used onaircraft?
2. For each of the following suggest a part on an aircraft thatneeds that particular material property: hardness, strength,elasticity, placidity, ductility, toughness, and brittleness.
3. Explain in why exceeding the yield point causes permeantstain, and how that is measured and calculated.
4. What do the temperatures on 1 & 2 of the iron– Carbonphase diagram indicate, shown in the presentation? What is thedifference between 3 & 5? Four (4) represents the meltedregion; will the composition of the alloy be the same?
