Al–Ga + As, Bi, Cd, Ge, Hg, In, Pb, Sb, Sn, Tl, Zn Aluminum–Gallium + Arsenic, Bismuth, Cadmium, Germanium, Mercury, Indium, Lead, Antimony, Tin, Thallium, Zinc systems
664 resistance to water at high temperatures of AlFeNiSi alloys (some also containing magnesium), to be used for canning nuclear fuel, was improved by increased silicon [1]. REFERENCE 1. S. Aas, etc., MA 1, 1985
Al-Ga + As, Bi, Cd, Ge, Hg, In, Pb, Sb, Sn, Tl, Zn Aluminum-Gallium + Arsenic, Bismuth, Cadmium, Germanium, Mercury, Indium, Lead, Antimony, Tin, Thallium, Zinc systems The quaternary equilibriums that result when the above elements are mixed have been briefly investigated by [1]. The three systems below were found to be simple eutectic ones*, with the eutectic point practically coinciding with one of the binary eutectics. In the AlGaGeSn system the eutectic is at approximately 92% Ga, 8% Sn, 293 °K; in the AlGaGeZn system the eutectic is at approximately 95% Ga, 5% Zn, 298 °K; in the AlGaSnZn system the eutectic is at approximately 82% Ga, 12% Zn, 290 °K; in the three eutectics the aluminum or germanium content is less than 0.10%. In the systems AlGaGeSb, AlGaSbSn and AlGaSbZn the compound SbAl is primary over most of the field and the quaternary eutectics are close to the binary or ternary ones. In the AlGalnSb system, the compounds SbAl, GaSb and InSb are completely miscible [2, 3]. In the SbAl-GaSb-InSb triangle the liquidus rises rapidly from the GaSb and InSb side to the AlSb corner. There should be a quaternary eutectic, liq. —» Al + Ga + In + (AlGaln)Sb, probably very close to the ternary, liq.—* Al + Ga + In at 14 °C, ~ 76% Ga, - 24% In. In all the other systems there are wide miscibility gaps in the liquid [1], as is to be expected from the binary or ternary diagrams. REFERENCES 1. H. Spengler, JIMMA 23, 812 2. L. Yu-Lung, etc., MA 2, 1905 3. J. Steininger, Met A 4, 110055 * In the two zinc-containing systems no account is taken of the compound ZnAl, because the work was done at a time when the existence of the ZnAl compound was not recognised.
