Abstract
The precipitate morphology of Ir-Nb alloys is altered by heat treatment. When Cuboidal precipitates were localized in rows along the 〈001〉 cube directions, the strength was lower than that of samples with cuboidal precipitates distributed uniformly, because of large, wide fcc channels. When plate-like or needle-like fcc phases were formed in cuboidal L12 precipitates, there was no large difference in the strength from that of samples with uniformly distributed cuboidal precipitates. This shows that Ir-Nb alloys deform by the bypass mechanism.
