The workability evaluation of wrought AZ80 magnesium alloy in hot compression

Improved mechanical properties of Mg–7.6Al–0.4Zn alloy through aging prior to extrusion

“…typically limit their strength and plasticity [1], and thus extensive effort has been directed toward achieving superior mechanical properties with wrought Mg alloys. Among the various high-strength extruded Mg alloys developed to date, AZ80 alloy (Mg-8.0Al-0.5Zn, wt.%) is currently utilized commercially for engineering applications due to its combination of relatively low material cost, moderate strength, reasonable ductility and good corrosion resistance [2][3][4]. However, further improvement in the strength of extruded Mg alloys would allow them to provide a viable alternative to other commercially used materials such as Al alloys, steels, polymers and ceramics.…”

Evaluation of the hot workability corresponding to complex deformation mechanism evolution for Ti–10V–2Fe–3Al alloy in a wide condition range

“…The non-basal slips increase with increasing temperature for they are strongly thermally activated. Quan et al (2011) reported that the m-value is influenced by non-basal slips and more such slip systems increase m-value. However, other plastic deformation mechanisms involving basal slips, twinning and micro-cracks decrease m-value.…”

Effect of temperature and strain rate on compressive response of extruded magnesium nano-composite

“…The continuum criterion for the evidence of flow instabilities is explained in terms of a dimensionless parameter by using the maximum irreversible thermodynamics extremum principle. The dimensionless parameter of microstructural instability is given below in equation (3) as discussed elsewhere [15]:…”

“…The mechanical properties of pure magnesium/alloys are enhanced by the addition nano-particulates, such as aluminium oxide, zinc oxide etc., at low volume fractions as reinforcements [13][14][15]. An Mg composite reinforced with 0.5 vol.% of nano-ZnO has a higher compressive yield strength than an Mg composite reinforced with 1.0 and 1.5 vol.% of nano-ZnO [16].…”
