“…Since 1808 when the first Mg was produced in quantity, the purity of commercially available Mg now exceeds 99.8%. Some useful characteristics of Mg include high stiffness, Young's modulus about 45 GPa at room temperature, high specific heat about 1.05 kJ (kg°C) −1 and a low melting temperature (∼650°C) [1]. Products produced from Mg and its alloys are readily manufactured by near-net shape casting.…”

Magnesium (Mg) alloys have received a significant interest in the past 20 years, owing to a nonlinearly increasing demand for lightweight structural materials. Magnesium extrusions alloys to date have had lower industrial uptake than their counterpart aluminium extrusion alloys, predominantly due to lower extrudability and formability, tension-compression yield asymmetry and no clear advantage in the specific strength. Any improvement in extrusion alloy properties requires a better understanding of the effects of alloy composition and processing conditions; and how these dictate the final alloy microstructure. This review sheds insightful information on the processing-microstructure-property relationships of extruded magnesium alloys. Historical and recent progress in magnesium extrusion alloys is critically reviewed, including the advances in extrudability, mechanical properties and microstructural characterisation. The challenges associated with the 'gap' in properties between the magnesium and aluminium extrusion alloys are identified, and prospects discussed regarding the development of high performance magnesium extrusion alloys.

“…Besides, the mechanical properties of RS/PM TAE542 alloy are superior to similar RS/PM Mg alloys made by other rapid solidification techniques. The tensile yield strength of Mg-5 wt-%Al-2 wt-%Zn-1 wt-%Si-1 wt-%Pr alloy made by the planar flow casting technique and Mg-7 wt-%Al-1 wt-%Zn-1 wt-%Y alloy made by the gas atomisation technique is 343 and 310 MPa, respectively [27]. That is because the melt-spinning technique gains a higher cooling rate during solidification, compared with gas atomisation planar and flow casting techniques.…”

The microstructure and mechanical properties of hot-extruded Mg-5Sn-4Al-2Ce alloy in the form of rapid solidification ribbons (RS-extruded TAE542) are investigated. The results show that rapid solidification causes ultra-fine a-Mg grains (250 nm) and massive dispersive Mg2Sn and Al11Ce3 particles (80–400 nm) in the rapidly solidified (RS)-extruded alloy. As a result, the yield strength and elongation of RS-extruded TAE542 alloy reached 366 MPa and 15.2%, increasing by 72 and 26%, respectively, when compared with that of hot-extruded TAE542 alloy made from a homogenised ingot (HI-extruded TAE542). This paper is part of a thematic issue on Light Alloys.

“…Mg alloys are the lightest metallic structural materials available. Their high specific strength, good damping capacity, high electrostatic shielding ability, and machinability enable Mg alloys to be widely used in various industries [1]. However, their rapid loss of strength at high temperatures restricts their use as structural materials in high-performance applications [2].…”

A TiNi shape memory alloy fibre-reinforced AZ31 Mg alloy matrix composite was fabricated herein by spark plasma sintering. The microstructure of the composite and the effect of prestrain on its strength were analysed. The phase transformation of TiNi was observed in situ, and the effect of temperature was monitored. Metallurgical bonding formed at the interface between the TiNi fibre and AZ31 matrix. The prestrain strengthening effect on the yield stress of the composite at 298 K was more dramatic than at 373 K, and the effect decreased with increasing prestrain. The prestrain strengthening effect on tensile strength of the composite was effective at both 298 and 373 K. Because of the difference between recovery stress of TiNi and prestrain-induced compressive stress, higher temperature strengthened the material more significantly than did prestrain application.
