A method for the production of components made of ceramic-matrix composite material, in the fields of aerospace engines and turbines and turbine systems and plants; according to the method, a preform of ceramic fibers is shaped and set in a draining mold, for example made of plaster; the fibers of the preform are impregnated with a suspension of ceramic powders, the liquid of which is drained by capillarity from the draining mold; simultaneously to draining, a suspension of ceramic powders is infiltrated between the fibers of the preform so as to fill the empty space left by the drained liquid; at the end of the steps of draining/infiltration a body is obtained with a solidified or compacted porous matrix, which is removed from the draining mold and is sintered.

A process for mass production of three-dimensional articles made of intermetallic compounds based on titanium and aluminium by an electron beam melting technology. The articles are produced in successive sections from powders of the intermetallic compound with which the articles are to be produced. For each section, melting of the powders preceded by a preheating step is performed.
