The change of magnetostriction and Young’s modulus of hot-rolled “Alfer” sheets, quenched in water and then subjected to heating cycles of one minute heating followed by air cooling at 300°, 400°, 500°, and 600°C were studied. The saturation magnetostriction increased abruptly at the initial step of heating time except at 300°C, and the tendency of the increase was the sharpest at 500°C, sharper at 600°C, and gentle at 400°C. All the specimens showed a distinct maximum at 500°C. The saturation magnetostriction in 45° direction showed a clear two-step variation at 400°C run. The change in Young’s modulus with heating time showed two different tendencies: (A) the young’s modulus decreases to a minimum, then increases to a maximum, and then decreases again; (B) the modulus gradually falls to a constant level. In 500° and 600°C process, the Young’s modulus in 45° direction of A·F-2 specimen (1 mm in thickness) showed abnormal change, and increased to a maximum and then decreased.
