Abstract
The cavity of a hollow turbine has its bottom equipped with a temporary means of obturation and is filled with a mixture of metal chips and a powder consisting of low melting metals, said mixture being subjected to a heating operation in order to join the chips with each other and with the walls of the blade by means of diffusion brazing of said fusible metal.
