“…Although the alloys presented in Figure 9 [17,18,53,69,[92][93][94][95][96][97][98][99][100][101][102][103][104] and (e) Mg-Sn [42,48,59,64,67,[105][106][107][108][109][110][111] extrusion alloys (and extruded under different conditions), it is apparent that the data points are clustered, and can be generally described by the Hall-Petch relationship [112,113] .…”

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.

“…7. The WH of both samples was evaluated by means of the macroscopic WH rate: h = dr/de, where r and e are the true stress and true strain, respectively [26,27]. The yield stress r 0.2 was subtracted from r. The (r -r 0.2 ) expresses the dislocation contribution to the flow stress during deformation.…”

The mechanical behaviour of AZ31 magnesium alloy sheet with the extrusion joint (EJ) was evaluated. Extruded joint of AZ31 alloy sheets was obtained by the hot extrusion process. Tensile tests were carried out along the extrusion direction at room temperature, and both the non-uniform plastic deformation and the fracture behaviour were studied. It is found that the samples with EJ present significantly deteriorated mechanical properties compared with the EJfree counterpart. Inhomogeneous microstructure distribution around EJ zone brings in the uncoordinated deformation due to the high density of f10 12g twins which were readily activated during plastic deformation.
