ABSTRACT
In the history of metal melt investigation there are roughly three stages [1]. At the first stage, it was established that a multi component metal melt was a much more complex object than an ideal solution and related to its design-theoretical constructs. At the second stage, it became clear that the poly terms of the properties of some liquid pure metals and especially alloys had inflections, jumps and other anomalies. The latter indicates that along with smooth structural changes there are jump-like changes, which are somewhat similar to phase transformations. The third stage of the experimental investigation of metal melts includes studying their properties during long isothermal holdings. The time dependences obtained have shown many different specific features, which, unfortunately, cannot be systemized and unambiguously explained yet.
