Aluminium matrix composites with alumina reinforcements give superior mechanical & physical properties. Their applications in several fields like automobile, aerospace, defense, sports, electronics, bio-medical and other industrial purposes are becoming essential for the last several decades. In the present work, fabrication of hybrid composite was done by Stir casting technique using Al 6061 a...

-s 211 WELDING JOURNAL ABSTRACT. Laser beam welding (LBW) has become common practice in the production lines of several industrial sectors including the electronics, domestic appliances, and automotive industries. The advantages of LBW over conventional fusion welding processes (mainly GMAW and GTAW) is the lower welding heat input and smaller weld pool and HAZ dimensions, which are associated ...

Metal matrix composites, in particular, Aluminium Matrix Composites are gaining increasing attention for applications in aerospace, defence and automobile industries. The use of nonconventional machining techniques in shaping aluminum metal matrix composites has generated considerable interest as the manufacturing of complicated contours such as dies. Electrical discharge machining (EDM) appear...

Abstract Aluminum oxide (Al 2 O 3 ) nanoparticles are capable of improving the material characteristics if reinforced to soft and low strength material. The major limitation in utilization Al alloy 6061 medium heavy stress applications such as automobile, defense, transportations, aerospace is hardness strength. In order overcome deficiency Al6061, nano-Al Al6061 matrix nanocomposite (AMNC) was...

Abstract In this work, a systematic study on the interactions between aluminum oxide films and TiB 2 grain refiner particles their effect refinement behavior have been conducted. Oxide were introduced into commercial purity melt by adding AA 6061 alloy chips while Al-3T-1B master alloy. Strong sedimentation of was observed in without chip addition during long-time settling. Most settled accumul...

The present work deals with assessment of tensile strength, hardness, fracture behavior and microstructural changes in welded Al-6061 plates. MIG welding has been done filler rod whereas no metal applied during TIG for comparing the results FSW, a filler-less solid-state welding. ultimate strength (UTS) MIGW sample found 75% 111% higher than that FSW TIGW samples respectively. Also, elongation ...
