Abstract: In the manufacture of billets from metal powder, in which the powder is enclosed in a container and subjected to isostatic pressure in a pressure furnace at such a temperature as to solidify the powder body, the container after the powder is introduced thereinto is degassed and thereafter supplied with a gas which is harmless to the powder material, which gas is present in the subsequent heating as a heat transfer agent circulating in the container.
