Abstract

Screening tests of binary high-temperature intermetallic compounds showed the Ru−Ta L10 structure to have room-temperature impact resistance and high-temperature strength. Twenty alloys based on RU11Ta9 have been studied for microhardness, elastic modulus, impact strength, and, in two cases, compressional stress-strain behavior. L10 lamallae are commonly seen, and their character on fracture surfaces correlates with relative toughness. The B2 phase is present in some alloys, also a twinned lamellar structure, and the beginnings of a martensitic transformation to the L12 form were observed in the transmission electron microscope at 93 K.
