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...

The thermal expansion behaviour of silicon carbide (SCS-2) fibre reinforced 6061 aluminium matrix composite subjected to the influenced thermal mechanical cycling (TMC) process were investigated. The thermal stress has important effect on the longitudinal thermal expansion coefficient of the composites. The present paper used experimental data of the thermal expansion behaviour of a SiC/Al comp...

The compressive mechanical properties of uniform and density-graded Al-6061 foams, produced by replication of polymer foams, are measured. hile the uniform foam shows compressive behavior characteristic of conventional (uniform) metallic foams with a near constant plateau stress, he density-graded foam exhibits a smoothly rising plateau stress. This behavior is modeled using a simple series com...
