摘要

Fe-Al-Ta eutectic composites with solidification rates of 6, 20, 30, 80 and 200μm/s were obtained by a modified Bridgman directional solidification technique and alloying. Moreover, tensile property and fracture behavior of Fe-Al-Ta eutectic composites were studied at 600 °C. The relationship between mechanical property and microstructure at high temperature was studied. Microstructure of Fe-Al-Ta eutectic is composed of Fe2Ta (Al) Laves phase and Fe (Al, Ta) matrix phase. In addition, the tensile strength at high temperatures is higher than that at room temperature. The tensile strength is increased with the increase of solidification rate. Moreover, fracture morphology transforms from cleavage fracture to dimple fracture as the solidification rate is increased at high temperatures.
