Abstract

Process for manufacturing binary or complex intermetallic compounds, whose melting point significantly exceeds the eutexy temperatures of the corresponding alloy systems, characterized in that two powders are prepared, one of the elements of the compound containing less than proportion in which it exists in said compound, but such that by heating this powder above the temperature of the richest eutectic in this element, a quantity of liquid comprised between 0 and 15% is created, the other powder containing the same element in proportion higher than that in which it exists in said compound, but such that by heating this other powder above the temperature of the richest eutectic in the other element of the compound there is creation of a quantity of liquid comprised between 0 and 15%; because these two powders are mixed in proportions such that the overall composition of the mixture is that of the desired compound; and because this mixture is compressed and fried according to the usual techniques, with a small gradient of the temperature as a function of time.
