抄録

The order-disorder transformation of hot-rolled “Alfer” sheets with 12.29 and 13.41 per cent of aluminum was studied. The results are summarized as follows: (1) The saturation magnetostriction of Alfer of 12.29 per cent aluminum composition in the ordered state after water quenching from just below critical temperature of order-disorder transformation was very close to that in the state after subzero quenching in liquid nitrogen from higher temperature than the critical temperature. (2) Under the same heat treatments as mentioned above, the young’s modulus of this specimen was largest in the disordered state quenched in water, next in the ordered state quenched in water, and smallest after subzero quenching in liquid nitrogen. (3) The intensity of magnetization of this specimen at H=50 Oe in disordered state was smaller than that in ordered state. (4) The intensity of magnetigation of this specimen at H=50 Oe, was somewhat dependent upon roll direction and showed a maximum at 45° to the roll direction. The property of specimen of 13.41 per cent aluminum composition was different from that of the above specimen in some measurements because of the complexity of phase change.
