    采用改良静滴法测量并通过软件的计算得到了4种商用镍基合金的密度.结果表明,随着温度的升高,4种液态镍基合金的密度逐渐减小,摩尔体积逐渐增大.与理想混合状态相比,液体镍基合金的摩尔体积出现负偏差.从而可以推测在合金中各种原子之间发生了调整.

    The densities of four kinds of molten Ni-based commercial alloys were measured with a modified sessile drop method, and calculated using the calculating software. It is found that the densities of the molten Ni-based commercial alloys decrease and their molar volume increase with increasing of temperature. Compared with the ideal mixing, the molar volumes of the molten Ni-based commercial alloys show negative deviations. It can be attributed to an accommodation between various atoms in the alloys.
