Abstract

Using the method of mathematical modeling, the effect of the initial temperature of the mold on the thermal conditions and kinetics of crystallization of chill castings of Cu₄₇Ni₈Ti₃₄Zr₁₁ alloy was investigated. According to the results, established that the value can have a significant effect on the final structure of the ingots. Depending on the value of, it is possible to provide thermal conditions under which formation of amorphous, amorphous-crystalline and fully crystalline states is possible. It is shown that the changes in the initial temperature of the mold are reflected in the final parameters of the microstructure of the resulting ingots, the average crystal size can vary from tens of nanometers to several micrometers.
