Abstract: The invention relates to a process for the production of titanium-based alloy members by powder metallurgy.This process consists of:(a) preparing a titanium or titanium alloy powder having a grain size distribution between 100 and 1000 .mu.m,(b) depositing on said powder a coating of a material such that on contact with the titanium or titanium alloy it forms a liquid phase at a temperature T.sub.1 which is below the allotropic transformation temperature T of the titanium or titanium alloy constituting the said powder,(c) introducing the thus coated powder into a mould, and(d) hot compressing this powder in the mould at a pressure of 10 to 30 MPa at a temperature between T.sub.1 and T for a time such that a complete densification of the powder is obtained.Application to the construction of discs for turbines with integrated blades.

Abstract: The cell comprises a structure of superposed film layers with at least two metallic elements insulated from each other for the supply of current to a cathode and to an anode. The cathode is formed by a porous cermet substrate coated with a thin film of solid electrolyte which consists of a mixture of refractory oxides in solid solution and which is in turn coated with a porous deposit constituting the anode. Current drainage between the metallic elements and the cathode and the anode is obtained on each side of the solid electrolyte by means of thicknesses of a conductive sponge.
