Abstract
Abstract The processing of intermetallic compounds by severe plastic deformation (SPD) methods is reviewed. In Ni3Al-based massive compounds or multiphase materials this leads to a disordered nanocrystalline structure. In TiAl, high-temperature SPD by multi-step forging produces sub-microcrystalline materials, but room-temperature SPD by high-pressure torsion results in a partial phase transformation. This is also the case for the σ phase of multiphase FeCrCo alloys.
