• The thermal expansions of FeCo alloys in the bcc range have been measured. The volume of the 30-70 at% Co alloys decrease at the order-disorder transition temperature T_c on ordering, and the expansivity of these alloys decrease as the long-range order parameter increases. The mean expansivities of the ordered 25-70 at% Co alloys are less than those of the disordered ones in the temperature range from 100° to 200℃. The volume due to the ordering at room temperature decreases in 27.5～33.3 at% Co and increases in 40～70 at% Co. The volume increase due to the ordering at room temperature of the 40-70 at% Co alloys is mainly attributed the expansivity in the ordered state.
