| 摘 要： | 用改良密度法对熔融Ni—Ta二元合金的液态密度进行了精密测量。结果表明：熔融Ni-Ta二元合金的密度随温度的增加而减少，但随合金中钽浓度的增加而增加：熔融Ni-Ta二元合金的摩尔体积随温度和合金中钽浓度的增加而增加，并对钽在熔融Ni-Ta二元合金中的偏摩尔体积进行了计算。 |

| Abstract: | The density of molten Ni-Ta alloys has been measured by a modified pycnometric method. It is found that the density of the molten Ni-Ta alloys decreases with a rise in temperature, but increases with the increase of tantalum concentration in the alloys. The molar volume of molten Ni-Ta binary alloys increases with the increase of temperature and tantalum concentration. The partial molar volume of tantalum in molten Ni-Ta binary alloy has been approximately calculated. |
| Keywords: | Ni-Ta alloy density modified pycnometric method molar volume tantalum |
