The refractory element Ta was added to L12-type Ni3(Si, Ti) intermetallic alloys in order to substitute for Ti. The microstructure and the mechanical properties of the alloys were investigated as a function of the Ta content. All the alloys were doped with 50 wt.ppm boron to suppress intergranular fracture. The alloys containing up to 5 at.% Ta showed an L12 single-phase microstructure, while
Effect of Mn addition on microstructure and mechanical Jan 25, 2016 · The effect of 0.5 wt% Mn addition on the microstructure and mechanical properties of cast Al2Li2Cu0.8Mg0.4Zn0.2Zr (wt%) alloy was investigated. Results showed that the grain size of Mn-containing alloy was smaller than that of Mn-free alloy in both the as-cast and solution treated state.
