抄録

The influence of aging treatment on the magneto-striction in Alnico 5 was studied by the use of a strain-gauge. The aging at about 600° which brings out the best magnetic property causes a minimum value in saturation magneto-striction. It is considered from the results of this study and of the previous study on the temperature dependence of the electrical resistance that in Alnico 5, a stable condition is formed by aging at about 600°. The precipitation arises by aging above about 650°. The aging at 725° causes a maximum value in saturation magneto-striction. And a slight transformation is suggested from the behavior of the starting point in magnetostriction curve and from the domain pattern. It is inferred that the phenomena may mean a start to the cohesion of precipitation.
