High-Temperature Properties of <italic>vacuum-melted</italic> Superalloys

IMPROVED high-temperature rupture strength and ductility of nickel-base superalloys has been obtained by utilization of vacuum melting and certain modifications in the nominal chemistry of these alloys.

A brief description of the melting technique and chemistry modifications is given in this page. The tensile and rupture properties of five nickel-base vacuum-melted alloys are reported for the temperature 1000–1600 F.
