Processing of 5083 Aluminum Alloy Reinforced with Alumina through Microwave Sintering

Microwave Sintering of Aluminum Alloys

Until 2000 almost all research in the microwave sintering area was confined to non-metallic materials. However, after the first report by Penn State in 1999 on full sintering of steel powders in microwave, now in the last few years there has been increasing interest in applying microwave energy for processing of variety of metallic materials. The present study is an extension of this work and r...

Microwave Sintering of Abrasion Resistant Alumina Liner Tiles

The need to move large volumes of highly abrasive materials, such as coal, grain, sand, and various waste products, places great demands on the piping systems through which they are conveyed. Excessive wear is a common problem, especially evident in the sections of pipe, which change the direction of flow of the abrasive material. . Due to their excellent wear characteristics, ceramic materials...

Synthesis of Nano Alumina Reinforced Magnesium-Alloy Composites

The main aim of this paper was to determine the amount of Al2O3 reinforcement that results into best combination of strength. Magnesium nano composites containing 3.5, 7.0 and 14 volume percentage of Al2O3 were synthesized through powder metallurgy route. Resistance of furnace sintering technique (heating rate: 49°C/min).Micro structural characterization revealed reasonably uniform distribution...

Characterization of Nanocrystalline Aluminum Alloy 5083 Powders Produced by Cryogenic Attrition

Laser Welding of Aluminium Alloy 5083

There are two laser welding mechanisms, keyhole mode and conduction mode. Keyhole welding is widely used because it produces welds with high aspect ratios and narrow heat affected zones. However keyhole welding can be unstable, as the keyhole oscillates and closes intermittently. This intermittent closure causes porosity due to gas entrapment. Conduction welding, on the other hand, is more stab...
