Aluminum/alumina composites are used in automotive and aerospace industries due to their low density and good mechanical strength. In this research, the effect of mechanical stirring of slurry in liquid-solid phase temperature and injection of alumina powder with inert gas (Ar) on microstructure and mechanical properties of Al-A356 alloy is investigated. In order to improve of the wettability a...

In this research, a novel method to decrease micro-residual stresses of fibrous composites by adding carbon nanotubes (CNTs) is proposed in detail. The negative coefficient of thermal expansion and the high young’s modulus of CNTs can be utilized to counterbalance the process induced residual stresses in composites. To this end, first, the effects of adding CNTs to the matrix of fibrous composi...

Reinforcement of aluminum and alloys with graphene has been intensively practiced by researchers in the past dozen years. The role Al4C3, which could be produced unintentionally or purposefully during composite production, was controversial until it found that nano-sized carbides were beneficial for strengthening composites. aluminum-graphene-nano-sized Al4C3 composites us using powder metallur...

Metal matrix composites (MMCs) are among the very important engineering materials by which the combinations of various properties can be achieved. The MMCs have the great potential for use in automobile and aerospace industries for possessing high strength, stiffness and hardness. The reinforcement types used in the composites are continuous, discontinuous, short, whiskers and particles. The at...

Reactive infiltration processing was used to fabricate bulk NiAl and fiber-reinforced NiAl composites. Homogenous, pore-free materials were obtained by chemical reaction between nickel and aluminum after complete infiltration with liquid aluminum of preforms of nickel wires (containing tungsten wires for the composites) with low surface-to-volume ratio, high permeability, and regular infiltrati...

Learning from imbalanced data, where the number of observations in one class is significantly rarer than in other classes, has gained considerable attention in the data mining community. Most existing literature focuses on binary imbalanced case while multi-class imbalanced learning is barely mentioned. What’s more, most proposed algorithms treated all imbalanced data consistently and aimed to ...
