Compression tests between 800 and 1200℃ and 10_-3 and 10_-1s_-1 and conventional transmission electron microscopy have been employed to investigate the high temperature mechanical behavior and the deformation mechanisms of the NbCr₂/Nb alloy with the composition Nb-22.5 at.% Cr, prepared by mechanical alloying and hot pressing process. The results show that the peak strength of NbCr₂/Nb alloy decreases with the increase of deformation temperature and the decrease of strain rate. The main deformation mechanism of Nb matrix is the slip of dislocation. While, the deformation mechanism of the Laves phase NbCr₂ is through by stack fault/ twins and partial dislocation.
