Abstract
The paper reports effect of small ternary addition of In on the microstructure, mechanical property and oxidation behaviour of a near eutectic suction cast Nb–19·1 at-%Si–1·5 at-%In alloy. The observed microstructure consists of a combination of two kinds of lamellar structure. They are metal–intermetallic combinations of Nbss–β-Nb5Si3 and Nbss–α-Nb5Si3 respectively having 40–60 nm lamellar spacings. The alloy gives compressive strength of 3 GPa and engineering strain of ∼3% at room temperature. The composite structure also exhibits a large improvement in oxidation resistance at high temperature (1000°C).
