Among the most promising candidates for high temperature structural applications, refractory complex concentrated alloys are serious candidates achieving - in some specific cases - superior mechanical properties to some nickel-based superalloys. In that respect, the most impressive results are currently obtained for B2 or BCC/B2 microstructures which may retain high specific strengths up to 120 MPa.cm3.g-1 at 1000°C. Thus, and to gain more insights into such enhanced properties, the present work aims at studying the behavior of a TiZr-rich B2 single phase material. After induction melting and appropriate heat treatments, the alloy is subjected to uniaxial compressive testing under quasi static conditions at room temperature. Attention will be drawn to the relationships between mechanical properties and underlying deformation mechanisms analyzed by post-mortem transmission electron microscopy observations. Results will also be discussed and compared with other classical B2 compounds.
