Q6.1 There are always imperfections in a crystalline structure. Perfect order never exists throughout crystalline materials on an atomic scale. All crystalline structures contain large numbers of defects and imperfections. Name and explain two types of defects in crystalline solid. Q6.2 Heat treatment may be used to improve the mechanical properties of some aluminium alloys. Heat treatment for aluminium alloys is done via a process called precipitation hardening also known as age hardening. Explain the steps of age hardening and name one example of aluminium alloy which can be strengthened by age hardening.
