Preparation & Characterization of Al-5083 Alloy Composites

Preparation and Characterization of B 4 C Particulate Reinforced Al - Mg Alloy Matrix Composites

This paper describes the fabrication and mechanical testing of Al-Mg-boron carbide particulate composites using stir casting technique. The size of the boron carbide particulates is ranging between 30 to 100 μm. The boron carbide contents are varied from 3 and 7% by weight and are dispersed in the alloy matrix. The mechanical properties of the castings, particularly their tensile properties and...

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...

Microstructure Characterization and Mechanical Properties of Al-SiCp Composites

In recent years the aluminum matrix composites are gaining wide spread applications in automotive, aerospace, defense, sport and other industries. The reason for this is their exciting properties like high specific strength, stiffness, hardness, wear resistance, dimensional stability and designer flexibility. The present work reports on mechanical properties and microstructure analysis of Al-Si...
