The magnetic and electric properties of the binary and ternary alloys involving iron, silicon and aluminium have been measured, and the relations of these properties to their respective concentrations have also been investigated. Those alloys containing 6_??_11 per cent of Si, 4_??_8 per cent of Al show specially excellent magnetic properties and their representative alloy has been shown to contain 9.62 per cent of Si, 5.38 per cent of Al. Some of its physical constants are as follows : the initial permeability, 35100; the maximum permeability, 117500; the magnetic hysteresis-loss, 28 egrs/cm3 per cycle: the coercive force, 0.022 oersteds; and the specific electric resistance, 81 microhms /cm3 at 20°.

The constitutions of the Al-rich alloys containing Cu and Mg were investigated by means of thermal analysis and microscopic examination. ation. From various constitutional sections taken as constant in Al-content or taken through the Al axis, the following conclusions were drawn: (1). In a range of Cu 50% and Mg 40%, the primary separations are (Al), CuAl2, S, T, β and X, where S and T being in equilibrium with (Al), denote ternary compounds Al13Cu7Mg8 and Al5CuMg4 respectively, β is an intermediate phase existing between Al and Mg and X is an unknown phase not determined in this investigation. (2). The ternary compounds Al13Cu7Mg8. and Al5CuMg4 were found to exist. (3). The uni-variant reaction lines were found to be: -Liq_??_(Al)+CuAl2, Liq_??_(Al)+S, Liq_??_(Al)+T, Liq_??_(Al)+β, Liq_??_CuAl2+S, Liq+T_??_S, Liq+X_??_S, Liq+X_??_T, Liq_??_T+β, and the in-variant points were; Liq (Al)+CuAl2+S, at 500°, Liq_??_(Al)+T+β, at 447°, Liq+S_??_T+(Al), at 465°, and Liq+X_??_S+T, at 525°. (4). It is concluded that the natural ageing of Duralumin and 24S-type Super-Duralumin is mainly concerned with the solid solubilily change of S-compound and CuAl2 or that of S-compound in Aluminium.
