The effect of uniaxial compression along the binary and bisector axes (up to deformations of -0.2%) on the current-voltage characteristics, the dynamics of breakdown development, and the lifetime of nonequilibrium charge carriers was experimentally studied for multivalleу n- and p-type $Bi_{1-x}Sb_x$ semiconductor alloys (0.10 $\leq x \leq$ 0.167) at a temperature of 4.2 K. As a whole, the results can be qualitatively explained on the basis of the available data on compression-induced variation of the energy spectra of these materials.
