Abstract

Modern ideas about the structure of liquid metals and alloys are considered. The main emphasis is placed on the cluster model and its structural parameters. The effect of chromium concentration in nickel-chromium melts on the change in the parameters of the cluster structure is shown. The calculation results are compared with the previously obtained experimental X-ray diffraction data and the results of studying the temperature dependences of the physical properties of nickel and its alloys with chromium in the liquid state. Attention is drawn to the fact that at a temperature close to 1900ºС the cluster radius becomes less than 10 Ǻ and these are the critical temperatures characteristic of binary and multicomponent nickel melts, upon reaching which structural changes occur in the melts and the metallic liquid becomes more equilibrium. and microhomogeneous.
