Abstract: Intermetallic compounds have many desirable properties as matrix-compatible 2-phase structural materials with good mechanical properties, and low diffusion rates due to their ordered structure. However, these materials show low strength at high temperatures and low ductility due to hydrogen embrittlement at room temperature. High-temperature strength and creep resistance of Fe3Al alloys are tried to be improved by alloying processes. In the present study, the effect of Tungsten addition on room temperature and high-temperature strength properties was investigated by applying a compression test at room temperature and 600 °C to Fe-28Al and Fe-28Al-0.1Y alloys. With the increase in tungsten content, an increase in strength was achieved.
