用改良静滴法测量液态Ni基合金的密度和摩尔体积

Density and Molar Volume of Molten Ni–Based Commercial Alloys Measured by Modified Sessile Drop Method

摘要:

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

Abstract:

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
