Abstract
A process for the preparation by sintering of molybdenum based alloys containing at least one reinforcing element, characterized in that at least one addition compound is introduced in the solid state into molybdenum used in the form of at least one of the components of the group consisting of the salts of molybdenum and the oxides of molybdenum, and that carbon is then added in sufficient quantity and the intimate mixture, after reduction of the molybdenum based component, is sintered at a temperature at which the said carbon at least partially reduces the addition compound. Addition compounds belonging to the group consisting of the mineral and organic compounds of titanium, zirconium, hafnium, thorium, aluminum, niobium, beryllium, boron and the rare earths are used.
