Abstract Under cold spray conditions, the modified Johnson–Cook model was adopted to perform single and multiple particle simulation for spherical elongated aluminum alloy- Al-6061 feedstock particles. The splat formations were realistically presented; temperature evolution throughout deposition process stayed below melting point of Al-6061, particles exhibited restitution impact velocities low...
Complex aluminium alloy components fabricated by powder metallurgy (P/M) offer the promise of a low cost and high strength-to-weight ratio, which meets the demands of the automotive sector. This paper describes the die compaction and sintering response of an atomised Al-6061 alloy powder containing Mg and Si produced by rapid solidification. A design of experiments is used involving three level...
In this research, surface composite layers containing nano sized TiB2, Al2O3-TiB2, ZrO2 and CNT particles have been fabricated on Aluminum alloy substrates by friction stir processing. The effects of different processing variables such as number of passes and strengthening particle distribution, hardness, and wear properties of surface nano...

Particle effects on friction and wear of 6061 aluminium (6061 AI) reinforced with silicon carbide (SIC) and alumina (AI203) particles were investigated by means of Vickers microhardness measurements and scratch tests. Unreinforced 6061 AI matrix alloy was also studied for comparison. To explore the effect of heat treatment, materials subjected to three different heat treatment conditions, i.e. ...
Abstract It is an underlying fact for the case of joining process especially welding to have optimized parameters achieve joints with outstanding mechanical characteristics. In current article, using stir-cast aluminum-based alloy (Al 6061) Al 6061/5%wt. silicon carbide, 6061/10%wt. and 6061/18%wt. carbide was welded underwater friction-stir process. Optimum [namely, tool rotating speed (N), (S...
The joining of a 6-mm thickness Al 6061 to AISI 1018 steel has been performed by the combined effects of fusion and solid state welding. The process is derived from friction stir welding (FSW) but with an adjustable offset of the probe location with respect to the butt line. Metallographic studies by optical microscopy, electron probe microscopy, and the utilization of the X-ray diffraction tec...
In this study, microstructure and mechanical properties of diffusion joints between 5754, 6061 and 7039 aluminum alloys and AZ31 magnesium alloy were investigated. Diffusion joints were done between the alloys at 440 °C, for duration of 60minutes, at 29 MPa pressure and under 1×10-4 torr vacuum. The interface of joints was studied using optical (OM) and scanning electron microscopy (S...
