Longitudinal and transversal magnetostrictions of rapidly quenched amorphous alloys in (Fe_<1-x>Co_x)_<80>P_<13>C_7 and (Fe_<1-x>Co_x)_<75>-Si_<15>B_<10> systems were measured in the saturation magnetization region at room temperature. Forced magnetostrictions of these alloys were also measured in the magnetic field up to 23 kOe. A three-terminal capacitance method and a modified dilatometric method of a suspension type were employed for the measurements. The magnetostriction constant obtained by multiplying a factor 2/3 by the difference between the longitudinal and transversal magnetostrictions is zero in the alloy with x=0.94, being positive in the range of 0<x<0.94 and negative in the range of x>0.94. This fact accounts for the remarkable low coercive force and high permeability of the alloy with x=0.94. The forced volume magnetostriction has been obtained to be about 23×10^<-10> in the alloy with x=0 ; it decreases monotonically with increasing x.
