1) Magnesium does not have 5 independent slip systems and therefore does not comply with von Misses criterion. Therefore, we expect total lack of deformation capacity in magnesium. However, to our surprise, we observe some deformation capacity in magnesium because 2) If you want to shape magnesium by deformation what temperatures would you select and WHY? 3) What is different in the behaviour of inclusions in molten magnesium as compared to, say Al or steel or whatever metal. 3) What is the categorical difference between H tempers and T tempers for aluminium alloys? Explain the following: a) T4 - Solution heat treated, and naturally aged to a substantially stable condition. b) How do we obtain "quarter hard” level?
7) If we observe ......... .... in the microstructure that means either the temperature was too high or the time length was too long for the solutionizing treatment. 8) If we quench the material during an artificial ageing treatment before the peak hardness is achieved and then keep it at room temperature what would we observe?: . Choose the incorrect expression: a) Hard alpha case and CP titanium are both due to interstitial elements that exist in air. b) Hard alpha case on a titanium part can be removed of a known depth by careful machining from the surface. c) Titanium alloys can show martensitic transformations if the alloy composition permits. d) Titanium is highly resistant to chlorium corrosion as long as the medium contains a certain level of moisture.
