Abstract: The present invention relates to producing refractory composite materials, practically poreless, and can be used for production of composite articles with increased size stability, wear resistance, high specific physico-mechanical properties and hardness, production of wear-resistant inserts in components and materials for tribo-technical purposes as well.The present method for producing a refractory composite material includes the steps of infiltration of a porous carbide work-piece by a metal resulting in preparation of an intermediate body, which is additionally treated in a melt of another metal at temperature exceeding the melting point of the metallic phase of the intermediate body, resulting in substitution of the metal in the intermediate body by the metal from the melt. The present invention extends the series of metals, which ban be introduced in composition of composite materials, and thus extends the application area of composite materials of this type.

Abstract: Es wird ein Gießverfahren unter Verwendung eines Gießkerns aus mineralischen Schaumkugeln beschrieben. Diese sind zu einer Matrix zusammengeklebt, wobei die Spalte zwischen den Kugeln Infiltrationskanäle für die Schmelze bilden. Der Gießvorgang gliedert sich in eine Andockphase, eine Infiltrationsphase und eine abschließende Druckphase. In der Infiltrationsphase dringt die Schmelze zumindest in den peripheren Bereich des Gießkerns ein und erstarrt dort. Dadurch entsteht eine Makrotragstruktur, die aus der Statik als Gewölbewirkung bekannt ist und den Abbau von Materialspannung im Werkstoff bei Angriff eines von außen wirkenden Lastkollektives auf den Gusskörper begünstigt.

Abstract: A method of manufacturing a preform for compounding use which. is to be impregnated with a molten metal to be compounded with a matrix material, is provided. The method includes the step of mixing short fibers, ceramic particles and a binder material together to make a mixture. The average of lengths of the short fibers is 100 to 200 µm while the volumetric percentage of the short fibers is 1 to 7 %. The content of the binder material in the mixture is 0.3 to 5.0 mass %. The method includes also the steps of forming the mixture so as to have a predetermined shape, and sintering the mixture at a temperature of 1000 to 1150 °C to form the preform. Thus, it is restrained that the preform is deformed or an un-reinforced region is formed in the compounded portion.

Abstract: Metal matrix composites are manufactured in a vacuum die casting machine. Solid aggregate material is placed in a die (2, 5), the die is evacuated, and molten metal is driven by a piston (4) to infiltrate the solid aggregate material where it subsequently solidifies to form a metal matrix composite.

Abstract: The present invention relates to a method of forming a refractory article including the step of forming a refractory material powder into an intermediate body having a shape and size corresponding to the desired shape and size of the article, chosing a carbide-forming metal or alloy as material for the intermediate body, exposing the intermediate body formed to a gaseous hydrocarbon or a mixture of hydrocarbons at a temperature exceeding the decomposition temperature for the hydrocarbon or hydrocarbons until the mass of the intermediate body has increased by at least 3 %, and thereafter exposing the intermediate body to a temperature of 1000-1700 °C in an inert atmosphere if the temperature during the foregoing method step was too low to ensure a complete carbidization of the intermediate body. The invention also relates to an article produced by said method.
