The behavior of a A356+0.5 wt%Cu alloy used to manufacture cylinder heads was studied. Samples were solutionized, quenched and aged at 200 °C for 0.1, 1, 10 100 h. TEM characterization showed that the short aging durations (up h), dominating hardening precipitates β″ rods, while long duration (100 dominance shifted Q-phase (Q′, Q″ precipitates). length diameter rods measured produce size distri...

The effect of the application forced convection during continuous solidification A356 aluminum alloy over microstructural parameters AlFeSi phases has been presented in this work. investigation made on fact that as an solidifies under action a rotating magnetic field; non-dendritic casting structure will be obtained. Al-Si studied using stirring equipment with permanent magnets. This device all...

Metal matrix syntactic foams have been fabricated via counter-gravity infiltration of a packed bed of recycled expanded glass particles (EG) with A356 aluminum alloy. Particle shrinkage was studied and has been utilized to increase the particles' strength and tailor the mechanical properties of the expanded glass/metal syntactic foam (EG-MSF). The crushing strength of particles could be doubled...
