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 ...
متن کاملKinetics 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 ...
متن کاملHydrogen permeance of palladium–copper alloy membranes over a wide range of temperatures and pressures
The permeance of Pd–Cu alloys containing 40, 53, 60, and 80 wt.% Pd has been determined over the 623–1173 K temperature range for H2 partial pressure differences as great as 2.6 MPa. Pure palladium and copper membranes were also evaluated. The Pd–Cu alloys exhibited predictable permeances that reflected the crystalline phase structures as shown in the binary phase diagram. Under conditions of f...
متن کاملHardness 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...
متن کاملHot 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...
