Hardness evolution of AZ80 magnesium alloy processed by HPT at different temperatures

Discs of an extruded AZ80 magnesium alloy were processed by high-pressure torsion (HPT) using 6.0 GPa up to 10 turns at different temperatures (296 K and 473 K). The disc surfaces and cross-sectional planes were examined before and after processing using scanning electron microscopy (SEM) and Vickers microhardness (Hv). The microhardness results at the surface show differences in the strength o...

Thermal stability and superplastic behaviour of an Al-Mg-Sc alloy processed by ECAP and HPT at different temperatures

An Al-3%Mg-0.2%Sc alloy was processed by ECAP and HPT at different temperatures. Afterwards, samples subjected to 10 turns of HPT at 300 and 450 K, 8 passes of ECAP at 300 K and 10 passes of ECAP at 600 K were annealed for 1 hour at 523 K and their mechanical properties and microstructure were examined using microhardness measurements and EBSD analysis. In addition, tensile specimens with simil...

Kinetics of SIMA AZ80 Magnesium Alloy

Semi-solid feedstock of AZ80 magnesium alloy modified by [trace] rare-earth Y element 10 (0, 0.2, 0.4, 0.8 wt.%) were fabricated by [strain-induced melting activation] (SIMA) in the form of 11 extrusion and partial remelting. The effect of Y addition on the microstructure evolution of [the] 12 extruded and [isothermally heat] treated alloy was observed by [using an] optical microscope (OM), 13 ...

THE DEFORMATION BEHAVIOR OF AZ31 MAGNESIUM ALLOY AT ELEVATED TEMPERATURES

AZ31 magnesium alloy is considered as a promising alloy in various applications and industries. Furthermore, to design a proper hot working process (rolling, forging and extrusion), the assessment of hot working behaviour of the alloy is necessary. Accordingly, the hot deformation behaviour of AZ31 alloy was studied through hot compression testing method This was carried out in a wide range of ...

Hot Deformation Mechanisms in AZ31 Magnesium Alloy Extruded at Different Temperatures: Impact of Texture

The hot deformation characteristics of AZ31 magnesium alloy rod extruded at temperatures of 300 °C, 350 °C and 450 °C have been studied in compression. The extruded material had a fiber texture with > < 0 1 10 parallel to the extrusion axis. When extruded at 450 °C, the texture was less intense and the > < 0 1 10 direction moved away from the extrusion axis. The processing maps for the material...
