• The authors have previously published a paper on eutectoid transformation in Al-Zn alloys, in which the mechanism of the transformation was closely studied and a stepped transformation, β→β′→β″→α+γ, was proposed. (This Journal, vol. 10, 1934, p. 718 ; Mem. Ryojun Coll. Eng., Inouye vol., 1934, p 83) Now in this paper, small quantities of Mg 0.002%∿0.3%, were added to specimens, nearly of the eutectoid composition and the effects of Mg on the said transformation were studied. The experiments were carried out on quenched specimens by means of hardness, electric resistance and dilatation methods. So small a quantity of Mg, 0.002%∿0.006% retards the changes remarkably, but still even in the case of 0.3% alloy some changes of properties were observed by ageing at room temperature On the other hand, the unusual characteristic of the intermediate structure, which appears by tempering at 100°∿150°, fades away owing to the presence of Mg. This effect is most remarkably observed between 0.01% and 0.02% of Mg-content, which shows that the presence of Mg causes some important changes in the inner parts of the crystal lattice. (This paper was read at the 12th General Meeting, 1934, of this Institute).
