Fundamental changes in notions of the metallic alloy’s nature

The article "Fundamental changes in notions of the metallic alloys nature" is a collection of ideas and experimental results that unequivocally indicate that modern ideas about metallic alloys should become to history of alloys. Here we present to the reader the results of experiments obtained on two binary alloys Ni₇₅Mo₂₅ and Ni₈₈Al₁₂, as well as on one ternary alloy Ni₅₃Mo₃₅Al₁₂. These data are identical to the data we presented earlier obtained on alloys of 17 binary systems and seven ternary alloys. Briefly, the main conclusions of the experiments are as follows:

·         Interatomic chemical interactions exist in all metal alloys at temperatures of both solid and liquid states.

·         Chemical bonds in alloys have an amazing property to change their sign at a certain temperature (there is a phase transition "ordering - separation").

·         The reason for this transition is the electronic transition "ionic bond ↔ covalent bond".

·         The process of formation of new phases in alloys begins with the formation of diffusion micro-pairs formed during the melting of the alloy.

Such considerable differences between the existing notions about the nature of alloys and those revealed in this work should lead to changes in the technology of heat treatment of alloys, in the binary phase diagrams and to a change in the principles of creating new alloys.
