Abstract
In order to determine the region of glass formation between the AsS and ErS compounds, we studied the methods of physicochemical analysis: differential thermal (DTA), X-ray phase (XRD), microstructural (MCA), as well as by measuring microhardness and density. The eutectic composition between the AsS and ErS compounds is 10 mol. % ErS and temperature 280oC. At a cooling rate v = 102 K / min, the glass transition region based on AsS reaches 10 mol. % ErS. Some physicochemical properties of alloys from the region of glass formation have been investigated. The area of homogeneity based on AsS reaches up to 1.5 mol. % ErS.
