ABSTRACT:
The present invention develops a manufacture method, via conventional liquid metallurgy, of finished and semi-finished metallic parts as casting, ingot, blooms and slabs in alloys base Fe, base Ni and base Co, microstructurally reinforced with complex molybdenum and titanium carbide particles, by means of their previous elaboration and latter addition to the molten alloy in the melting furnace. Then, when the alloy solidifies, they are inserted and distributed within the grains of the base metallic matrix, enhancing their mechanical properties and behavior at room as well as at high temperatures.
