ABSTRACT:

An issue concerning distribution of temperature field in solid phases in melt during contact melting of bodies considering the absorption of hidden heat of molten metals has been solved. It was revealed that the temperature decrease in the melting zone due to the hidden heat of phase interactions does not exceed several degrees. That is why the adsorption of this heat cannot significantly affect the processes of contact melting in eutectic couples.
