    摘要:

    采用改良靜滴法測量并通過軟件的計算得到了4種商用鎳基合金的密度。結(jié)果表明,隨著溫度的升高,4種液態(tài)鎳基合金的密度逐漸減小,摩爾體積逐漸增大。與理想混合狀態(tài)相比,液體鎳基合金的摩爾體積出現(xiàn)負偏差。從而可以推測在合金中各種原子之間發(fā)生了調(diào)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
