Thermodynamic properties of liquid alloys of 3d transition metals with metalloids (silicon, carbon and boron)

摘要: Abstract A survey of the experimental investigations thermodynamic functions formation liquid binary and ternary alloys 3d transition metals (Tr  Cr, Mn, Fe, Co, Ni, Cu) with metalloids (Si, C B) is presented. The data for 19 (such as TrFeC, TrBC, TrSiC TrSiB) 17 border systems are reviewed. effects microheterogeneous structure iron chromium carbon boron described. indicate existence attractive forces between unlike atoms in all studied. cobalt-rich regions FeCoC CoSiC melts, where athermal solutions exist repulsive take place, an exception. correlation structural parameters excess at infinite dilution discussed. Model calculations glass-forming tendency (GFT), based on concentration dependence integral enthalpy mixing stoichiometry associates systems, allow range glass to be estimated.
