Abstract
Nb–16Si–2Fe in situ composite consisting of an Nb solid solution and the intermetallic phases Nb3Si, Nb5Si3 and Nb4Fe3Si5 were synthesized by hot pressing sintering to yield a fine microstructure with all four phases being in the size of micrometer range. The tensile elongation of this composite reaches 2 and 95% at room temperature and at 1300 °C, respectively. At 1350 °C and higher temperature, the material exhibits superplasticity. The tensile elongation reaches 512% at 1450 °C.
