چکیده مقاله:
AZ۳۱ 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 AZ۳۱ alloy was studied through hot compression testing method This was carried out in a wide range of temperature (۵۲۳K to ۷۸۳K) and strain rates. The obtained true stress-true strain curves and final microstructures were examined and a partial melting was realized at ۷۴۰K. It was concluded that the presence of liquid did change the deformation mechanisms thereby affecting the flow behaviour.
