Obtaining Composite Materials with Technological Role by Incorporating Granular Particles in Metal Matrix

摘要

Our paper aims to develop new materials in view of meeting the requirements of reducing pollution in steel plant production. The concept of composite with technological role based on creating new complex metal matrix with solid particles in granular form has multiple purposes, among which we mention reduction of pollution in steels department and reduction of economic losses through recovery and reusing of granular ferroalloy particles. This paper proposes a method and technology for obtaining composite materials using A6061 aluminium alloy as matrix and granular SiC disperse particles. Due to its high carbon content (30%), the composite can be used as complex deoxidiser and decarburization agent in steel elaboration. For the preparation of these composite A6061/SiC, the Stir Casting Vortex method has been considered in order to ensure a high embedding yields in granular state and it was with conducted a rigorous control of process parameters (temperature, speed of rotation, improved ways of introducing particles in granular state). The obtained composites have been characterized for morphology, chemical composition and structural analysis by scanning electron microscopy with energy-dispersive X-ray spectroscopy and X-ray diffraction methods.
