Investigation of phase transformations by in-situ neutron diffraction in a Co-Re-based high temperature alloy

Original language description

In-situ neutron diffraction at high temperatures was used to investigate phase transformation in a Co-Re-based alloy. Stability of carbides and transformation of Co matrix from epsilon (hcp) to gamma (fcc) phase were studied. The epsilon = gamma phase transformation exhibited a large hysteresis with temperature. The alloy has a complex microstructure with Cr23C6. TaC and sigma phase stable over a wide temperature range. The hysteresis is the result of composition interplay between Co-matrix and other phases, e.g. Cr-carbide and sigma. TaC is stable at high temperatures up to 1300 degrees C.
