- Abstract
Two medium-entropy alloys, NbZrTi and NbHfZrTi, were prepared by arc melting. Both NbZrTi and NbHfZrTi alloys are composed of simple body-centered cubic (bcc) solid solution phase and exhibit dendritic structure. After being homogenized, both NbZrTi and NbHfZrTi alloys are still composed of the single bcc solid solution phase, but the microstructure of the two alloys transforms from the dendritic structure into the polycrystalline structure. Two alloys display significantly work-hardening effect during compression at room temperature and show relatively good deformation plasticity during compressive deformation at room temperature. For NbZrTi and NbHfZrTi alloys, the dynamic recrystallized grains form along the boundary during compression at the temperatures of 1073 and 1273 K.
