Use of Thixoforming as a Manufacturing Method for Metallic Composites

Original language description

Thixoforming is one of the members of the family of semi-solid forming processes. It is possible to obtain complex shape of materials by this method and unconventional microstructures can be achieved due to its thixotropic properties. However, in this study thixoforming was used not only as forming method but also as a manufacturing method. Metallic composites were manufactured by a process of integration of powder metallurgy and semi-solid production technique. The mixture of Co72.5B15Si12.5 alloy and Fe powders become partially melted, compressed mechanically in semi-solid state and filled intricate cavities. Without changing alloy structure, it could be possible to reinforce it with Fe powders. Moreover, the final shape of the product could be achieved at the same time. Prior to the process, Co72.5B15Si12.5 alloy obtained in the form of stick was characterized by X-ray diffraction (XRD), scanning electron microscopy–energy dispersive spectroscopy (SEM–EDX), differential thermal analysis-thermogravimetry (DTA-TG), light microscope and micro-hardness machine. The stick was milled to get alloy powders and they were blended with iron. Characterization of the structures of the composite material was performed. It was concluded that the heating process of iron and alloy powders provides the formation of compact metal matrix composites.
