Description
Summary:Metal powders are used in industry for a diversity of products and applications. Metal matrix composites are materials developed through advanced methods with increased characteristics that surpass those of conventional materials. In recent years, the aluminum alloy matrix composites (AlSiX/graphite, AlSiMg/SiC, Al/SiC) are considered better substitute materials for steel components because of their higher strength-to-mass ratio which results in significant mass savings, these materials being successfully used in the construction of automotive components such as brakes and clutches. The paper presents a study concerning the specificities of the sintering technology using solar energy of an AlSi12–SiC hybrid composite, made by powder metallurgy performed at PROMES-CNRS at Font-Romeu-Odeillo-France (MSSFs facility furnaces). Based on the collected data, conclusions could be drawn on the heating mode and the effect of the concentrated power of the parabola on the sintering curves recorded by thermal analysis. The qualification of the sintered samples is performed by structural, DIL and DSC analyses.
