摘要：
Density of Al86Ni4Co4R6 (R = Nd, Gd, Yb) glass-forming alloys was studied using the absolute variant of gamma-absorption method. It was found that these alloys have a wide interval of two-phase zone and non-classic way of density transformations from solid to liquid state. The temperatures of solidus, liquidus, intermediate reactions were obtained by DTA as well as relative changes of density from solid to liquid states were determined. The coefficients of volumetric thermal expansion and values of molar volume for the investigated alloys were calculated basing on the experimental data.
