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...
Metal matrix composite (MMC) is engineered combination of the metal (matrix) and hard particle (reinforcement) to get tailored properties. MMCs are either in use or prototyping for the space shuttle, commercial airliners, electronic substrates, automobiles, golf clubs, and a variety of other applications.In this study, carbon nanotubes (CNTs) reinforced aluminum MMCs were synthesized by DPDS fo...
automotive and aerospace industries are required to light materials which have high properties. this causes to reduce production cost and fuel consumption. one of these advanced materials that have been attracted at these decades is particulate metal matrix nanocomposites. these materials have a combination of ductile matrix alloy properties and ceramic reinforcement nanoparticles. powder metal...
Fabrication and characterization of aluminum matrix composites containing different volume fractions of Ni3Al powder (5-40 Vol%) were investigated. Ni3Al powder was produced by mechanical alloying of elemental nickel and aluminum powder mixture. Al-Ni3Al composite parts were prepared using a powder metallurgy route involving two stages Al and Ni3Al powder mixtures were first compacted under 500...

Metal Matrix composites (MMCs) are light weight, high-strength materials with potential application in areas such as automobile, aerospace, defence and other industries. MMCs are projected to significantly reduce the overall weight of the vehicle and aircraft while maintaining satisfactory structural strength. Micron and Nano-sized ceramic particle reinforced aluminum matrix composites fabricat...
In this research, the production of Aluminum matrix composites (AMCS) consolidated by hot powder extrusion along with physical and mechanical properties of extruded bars have been studied. The matrix alloy was prepared from elemental powders of Al and 10wt% Ti. The composites comprises 5,10,15 or 20 vol% SiC or Al2O3 particles with an average size of 5 micron. The powder mixtures were sealed ...
The aluminum bronze matrix alumina composites using hot press and resin infiltration were investigated to study their porosities, hardness, bending strengths, and microstructures. The experiment results show that the hardness of the sintered composites with the decrease of porosity increases. The composites without and with resin infiltration have about HRF 42-61 of about 34-40% of porosity and...
Aluminum-based composites find its importance in the field of automobile and aerospace industries owing to their improved mechanical and microstructure properties are utilized for producing cylindrical components in LM6 alloy. Among all types of metal matrix composites (MMCs), considerable attention has been paid towards synthesis and characterization of aluminum matrix composites due to its li...
Our study proposes in situ synthesis of cold-rollable aluminum nitride (AlN) reinforced aluminum matrix composites with attractive thermal properties via arc plasma-induced accelerated volume nitridation (APAVN). Within three minutes of repeated APAVN using commercial nitrogen gas, volume fraction of AlN increased up to 40 vol%, which is the highest value ever reported by in situ nitridation of...
