In this study, ultrafine grained 2024 Al alloy based B4C particles reinforced composite was produced by mechanical milling and hot extrusion. Mechanical milling was used to synthesize the nanostructured Al2024 in attrition mill under argon atmosphere up to 50h. A similar process was used to produce Al2024-5%wt. B4C composite powder. To produce trimodal composites, milled powders were combined w...

A simple physically-based model for the abrasive wear of composite materials is presented based on the mechanics and mechanisms associated with sliding wear in soft (ductile)matrix composites containing hard (brittle) reinforcement particles. The model is based on the assumption that any portion of the reinforcement that is removed as wear debris cannot contribute to the wear resistance of the ...

Present paper reports an overview on the processing, corrosion behavior and applications of various metal matrix composites with a special focus on iron based metal matrix nanocomposites. As iron has a much higher melting temperature compared to aluminum, copper and magnesium therefore it is synthesized using powder metallurgy technique. P/M technique is widely used because it provides microstr...

Cu-Al composites are widely applied materials exhibiting advanced properties of both matrix metals. Controlling the brittle interfacial phases is a key factor in improving strength composites. This paper studied formation process fabricated by continuous composite casting. The phase sequence, growth direction and mechanism were clarified via element marking thermodynamic calculations. spatial d...

Abstract This paper aims to study the mechanical properties of hybrid polymer composites and addition primary secondary fillers nano-aluminum oxide nanographene Kenaf epoxy composites. The vacuum bagging method was used fabricate advantage using is reduce blowholes. weight ratio fiber 50%–60%, matrix 40%, 0%–6%, 0%–3% considered. Mechanical like Tensile strength, Young’s modulus elongation, fle...

In this investigation ‚the fracture toughness of A356 containing15%SiC composite was studied. Al/SiC composites have been considered because of their mechanical and erosion properties .Low fracture toughness in Al/SiC as compared with Aluminium alloys is one of its disadvantage. In this study at first A356 alloy was melted in a smelting electrical furnace then poured into the mould. A356-15% Si...
