The strength of metals and their alloys are enhanced by adding secondary reinforcement particles like Conventional crystalline and non-crystalline particles such as SiC, glass and Al2O3. These particles provide weak interfacial bonding due to the crystallographic structure mismatch or undesirable interface reaction products. Quasicrystals provide strong interfaces with the matrix due to their low interfacial energy. Their low strength and stiffness make them useful in non-critical stress applications such as instrument panels, seat frames and gear box housings. Reinforcing quasicrystals to Mg alloys greatly enhances their strength or stiffness. The literature on quasicrystal (in-situ and ex-situ) reinforced Mg alloy composites are critically reviewed to show the importance of quasicrystal reinforcement in Mg alloys and the effect of different manufacturing process technologies such as casting process, powder metallurgy, hot extrusion on mechanical properties.
