The preliminary results of studying transformation phenomena in nickel-cobalt alloys

Activity of Components in Liquid Alloys of the Iron-Cobalt-Nickel System

“…Velisek and co-authors [13] determined the activities of the components of the ternary system in a limited range of compositions by measuring the saturated vapor pressure at 1227oC, i.e., in the solid state. In [14], the activity of each of the components of the Fe3Co3Ni system was determined at 1200 31650oC, using a Knudsen cell combined with a mass-spectrometer.…”
