    摘要： Nickel alloys comprising less than 25% by volume of .gamma.' precipitate and containing 23 to 37% by weight of chromium and in addition a trace to 1.7% carbon, 0.3 to 4% by weight of platinum and/or 0.3 to 8% by weight of ruthenium, a trace to 1.5% by weight titanium and/or a trace to 1.5% aluminium the balance being nickel. The alloys combine improved corrosion resistance with high mechanical strength. Major improvements in mechanical strength seem to be obtained by adding small amounts of titanium and/or aluminium. The alloy is especially suited for use in contact with molten glass for example in a centrifugal spinner.

    摘要翻译： 镍合金包含少于25体积％的γ'沉淀并含有23至37重量％的铬，另外还含有痕量至1.7％的碳，0.3至4重量％的铂和/或0.3至8重量％ 的钌，痕量至1.5重量％的钛和/或痕量至1.5％的铝，余量为镍。 合金结合提高了耐腐蚀性和高机械强度。 通过添加少量钛和/或铝，似乎可以获得机械强度的主要改进。 该合金特别适用于例如在离心旋转器中与熔融玻璃接触。
