抄録

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.
