The thermal expansion as well as magnetic properties have been studied systematically for amorphous Fe80-xCrxP13C7 alloys (0 ≦ x ≦ 20). It have been found that the Invar effect becomes small gradually with increasing Cr concentration and it almost disappears when the Cr concentration exceeds 6 at%. The spontaneous volume magnetostriction has been estimated, which is proportional to the square of magnetic moment on Fe atom, independent of Cr concentration.
