Metals and their alloys possess crystalline structures that may be altered to change their mechanical properties. 4. (a) Illustrate, with the aid of a diagram, substitutional AND interstitial strengthening mechanisms in metal alloys. (b) With respect to microstructural features in metals, describe how the hindrance of the movement of dislocations through a lattice crystal structure strengthens metals and/or metallic alloys. Given the equilibrium phase diagram (a) below, briefly describe (c) the mechanisms of precipitation hardening/strengthening of an aluminium alloy making reference to the transitions shown in (b) below to X, X to A, X to D, A to B and A to C.
