Abstract
The object of the invention is a reactive sintering method of forming intermetallic materials such as TiNi, TiAl which includes the preparation of a mixture of elemental metallic powders in desired proportions (1) (2), the compression (3) of the mixture of these elemental powders so as to obtain a tablet of powders, then the cladding (4) of this tablet of powders in a cladding resistant to pressure and heat, the clad product then being subjected to a reactive sintering (5) to obtain the intermetallic compound and to a final hot densification operation (6) . Generally, the cladding is removed (7).
