摘      要：Two medium-entropy alloys,NbZrTi and NbHfZrTi,were prepared by arc *** NbZrTi and NbHfZrTi alloys are composed of simple body-centered cubic(bcc)solid solution phase and exhibit dendritic *** 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 *** alloys display significantly workhardening effect during compression at room temperature and show relatively good deformation plasticity during compressive deformation at room *** NbZrTi and NbHfZrTi alloys,the dynamic recrystallized grains form along the boundary during compression at the temperatures of 1073 and 1273 K.
