Laboratory apparatus for high temperature forging under vacuum or inert atmospheres.
Rev Sci Instrum 1972 Jun; 43(6):947-948
An apparatus was designed, constructed, and used to forge refractory metal specimens at temperatures up to 1,900 deg c under a vacuum or an inert atmosphere. The electrical resistance heater with radiation shielding located inside the vacuum chamber allowed good temperature control. Simultaneously with the forging stroke, the specimen was automatically moved onto the anvil below the heating element, where it was immediately forged. The apparatus has the potential for operation at considerably higher temperatures and for multiple forging blows if required.
