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 ...

Hydrodynamics of a Gas-Solid Fluidized Bed at Elevated Temperatures Using the Radioactive Particle Tracking Technique

Effect of temperature on hydrodynamics of bubbling gas-solid fluidized beds was investigated.  Experiments were carried out in the range of 25-600 ºC and different superficial gas velocities in the range of 0.17-0.78 m/s with sand particles. Time-position trajectory of particles was obtained by radioactive particle tracking technique. These data were used for determination of mean velocitie...

Microstructural Evolution of Roll Bonded Al-Clad Stainless Steel Sheets at Elevated Temperatures

The cold roll bonding of Al on AISI 304L stainless steel was carried out to fabricate the Al/304L/Al clad sheet composites. The maximum bond strength of 20 N/mm was acquired just by 38% reduction, for which the tearing of the aluminum sheet occurred during the peeling test. The microstructural evolution during subsequent postannealing heat treatment was systematically studied based on the impur...

Numerical Simulation of IGBTs at Elevated Temperatures

In this paper we present a 2D finite difference device simulator which has been developed to underpin the design and optimisation of power IGBTs. The simulator has been used to investigate the effect of elevated temperatures on the performance of the IGBT for use in environments where ambient temperatures up to 200°C are likely. The preliminary results of this investigation are reported here.
