An extensive study on the order-disorder transformation of hot-rolled “Alfer” sheets with 12.29 per cent of aluminum was undertaken. The saturation magnetostriction in ordered state after furnace cooling showed large value, but that in disordered state after water quenching was relatively lower, and the degree of decrease reached about 60 per cent in some direction. The saturation magnetostriction after subzero quenching in liquid nitrogen stood midways between the values in the two states mentioned above. The Young’s modulus was largest after water quenching, next after furnace cooling, and smallest after subzero quenching in liquid nitrogen. The saturation magnetostriction and the Young’s modulus rose slightly when the specimens were heated at the lower temperatures 100° or 300°C after subzero quenching in liquid nitrogen. The electrical resistivity was largest after water quenching, next after subzero quenching in liquid nitrogen, and smallest after furnace cooling. The density was largest after furnace cooling, next after subzero quenching in liquid nitrogen, and smallest after water quenching.
