The invention relates to a process for shaping a material by isostatic compression at a temperature of at least 1300°C of a powder of said material in a tight sheath. The sheath is made from titanium or a titanium alloy and is internally coated with tantalum in such a way that the sheath can be embrittled during hot isostatic compression by the diffusion of, tantalum into the titanium or titanium alloy in the presence of, oxygen. In general the titanium sheath is coated with tantalum by spraying in the presence of oxygen. The use of such a sheath makes it possible to avoid the operation of eliminating the sheath chemically or mechanically conventionally necessary in such processes. B 9491.3 …
