The57Fe Mössbauer spectra have shown that the hyperfine field of DyFe10Si2 alloy and its quadrupole splitting at the 8i sites change steeply at 210 K, which are attributed to the spin reorientation transition. The stabilizing elements for the formation of the ThMn12-structure can affect on the spin reorientation transition temperature. The differences of spin reorientation transition temperature of DyFe10Si2, DyFe10V2 and DyFe11Ti alloys had been discussed. The quadrupole splitting at 8i sites of DyFe10Si2 alloy changes its sign at 210 K.
