"Manufacturing, microstructure and wear resistance of novel hot extruded Fe based metal matrix composites";
Materials with high resistance against abrasive wear are of high interest for many tool applications, e.g. in mining industry. These materials usually contain a large amount of hard ceramic phases embedded in a metallic matrix and can only be manufactured by powder metallurgy, most often via hot isostatic pressing. Here a new manufacturing route via powder presintering and direct hot extrusion is presented, which enabled manufacturing of Fe based metal matrix composites with up to 30% of fused tungsten carbide (FTC, WC/W2C) or titanium carbide (TiC). The matrixes chosen are hot and cold work tool steels. The manufacturing process is elucidated and microstructures formed are presented. The microstructure-property relation of the new Fe based MMC is discussed.
