“…The densities of liquid Ni-Co alloys with 20.10-80.10 mass%Co reported by Watanabe et al 4) also decreased with increasing the temperature ranging from 1784 K to 1948 K, but the temperature coefficient is smaller than that obtained in this work.…”

“…The densities of liquid Ni-Co alloys at 1823 K reported by Dizhemilev et al 5) also changed with Co concentration in the form of a wavy line but increased slightly with increasing the Co concentration below 16 mass%. This is in contradiction with the results reported by Watanabe et al 4) Sung et al 6) cited measured densities of five Ni-base superalloys but did not indicate any details of the measurement method.…”

“…Eremenko and Naidich 3) measured the density of Ni-Cr alloys in liquid and ''mushy'' (ie solid+liquid) states for Cr concentrations between 9 and 57 mass% using the large drop method. Watanabe et al 4) and Dizhemilev et al 5) measured the densities of liquid Ni-Co alloys. Watanabe et al 4) reported that densities of liquid Ni-Co alloys (for Co concentrations between 20 and 80 mass%) decreased with increasing temperature in the range (1784-1948 K).…”

The modified sessile drop method (MSDM) and modified pycnometric method (MPM) have been employed to measure the densities of liquid Ni-Co, Ni-W, Ni-Ta and Ni-Al alloys precisely. In the case of Ni-Al alloys measurements were also made in the ''mushy'' state where both solid and liquid coexist. There was a good agreement between the values measured by the two methods. The density of liquid Ni-base binary alloys from the melting points to 1833 K and that of Ni-Al alloys in the mushy state decrease linearly with increasing temperature. The temperature coefficient of the density of Ni-base binary alloys measured in this work was regressed as a quadratic function of the concentration of alloy element. The measured density of Ni-base binary alloys at any required temperature can also be expressed as a quadratic function of the concentration of alloy element. The recommended equations for the density of Ni-base binary alloys were obtained as a function of composition and temperature by regressing the density values measured by both MSDM and MPM. The calculated values from the recommended density equations show good agreement with those obtained with both methods.

“…Furthermore, there are very few reports on the measurement of the density of Ni-based alloys in relation to the effects of composition and temperature. [1][2][3][4][5][6][7] There are no reports on the measurement of the densities of liquid Ni-based multi-component model alloys such as ternary and quaternary alloys.…”

The modified sessile drop method (MSDM) and the modified pycnometric method (MPM) have been employed to measure precisely the densities of liquid nickel-based ternary (Ni-Co-Al) and quaternary (Ni-Co-Al-Cr, Ni-Co-Al-Mo, Ni-Cr-Al-Mo) alloys and four commercial superalloys in liquid and mushy states. There was a good agreement between the values measured by the two methods. The measured densities of liquid model alloys and commercial superalloys in liquid and mushy states decreased linearly with increasing temperature for the experimental temperature range. The temperature coefficient of the density of liquid ternary Ni-Co-Al alloys measured in this work can be represented as a quadratic function of the aluminium concentration in the alloys. The density of liquid Ni-Co-Al alloys can be expressed as a function of both temperature and aluminium concentration in the alloys. The recommended equations for the densities of liquid nickel-based ternary and quaternary alloys and four commercial superalloys in liquid and mushy states were obtained by analysing density values measured by both MSDM and MPM. The calculated values from the recommended density equations show good agreement with those measured by both MSDM and MPM.
