  • Patent number: 4447390
    Abstract: A method for hot-consolidating powder of metallic and nonmetallic composition and combinations thereof to form a densified compact at a predetermined temperature and pressure at which the powder is transformed into a compact comprises the steps of filling the cavity of a container with a powder, such as a superalloy, to be compacted and hermetically sealing the container. The method is characterized by the steps of heating the container within an autoclave having an inert gas therein, such as argon, to an intermediate temperature, then pressurizing the autoclave to an intermediate temperature and thereafter raising the temperature to thereby increase the pressure and, consequently, reach the temperature and pressure to effect compaction or densification of the compact or article.
