The current work is concerned with the synthesis of aluminium (AA6061-T6) matrix composites (AMCs) reinforced 15 and 20 weight percentages silicon nitride (Si3N4) particulates using indigenously fabricated electric stir casting furnace bottom discharge arrangement. major concern in AMCs ceramic particles wettability route, it was overcome by adding 2% magnesium melt, proper incorporation time, ...

A more contemporary variation of the friction welding procedure, stud welding, is promising for military, space, automotive and naval applications. The joining steel/aluminium matrix composite joints has been crucial in many these In all applications, strength dissimilar joint a critical consideration. Heat-affected zones arise because heterogeneous temperature distribution change thermal chara...

In this study, aluminum (Al) matrix reinforced with micro-particles (30 µm) and nano-particles (50 nm) boron carbide (B4C) were used to prepare Al-2.5%wt., B4C nano-composite and micro-composite, respectively, using mechanical alloying method. The mixed powders were mechanically milled at 5, 10, 15 and 20 hrs. The XRD results indicated that the crystallite sizes of both the micro-composite and ...

This study visually compared the radiopacity of seven restorative materials (3 resin-modified glass-ionomer cements, 3 polyacid-modified composite resins, and 1 conventional glass-ionomer cement) to a sound tooth structure sample, and an aluminium stepwedge. All hybrid materials were more radiopaque, except for one resin-modified glass-ionomer cement, than both the tooth structure and conventio...

Metal matrix composites (MMCs) have become attractive for engineering structural applications due to their excellent specific strength and are increasingly seen as an alternative to conventional materials, particularly in the automotive industry. In this study, a historical background on the development and application of metal matrix composites for automotive brake rotors is presented. The dis...

Aluminum matrix composites (AMCs), reinforced with ceramic particulates, have significant applications in the field of aerospace, marine, automobiles, sports and recreation. Al-TiC particulate composite has better potential for high-temperature applications. The corrosion behaviour of Al 6061-TiC particulate composites prepared by stir casting route, has been explored in chloride medium using e...
