A cardinal change in heat treatment of metallic alloys

Abstract

This article shows that the current heat treatment, based on the misconceptions of the last century, should be. Here we present to the reader the results of experiments obtained on two binary alloys Ni75Mo25 and Ni75Co25, as well as on one ternary alloy Ni50Mo25Co25. These data can be considered similar to the data we presented earlier obtained on alloys of 17 binary systems and 7 ternary alloys. The article gives the experimental evidence that all processes occurring in the metallic alloys during heat treatment owe their origin to interatomic chemical bonds (ionic and covalent) that exist at all temperatures of the condensed state. This means that at each heating temperature of the alloy, its own microstructure forms, which differs from microstructures at other temperatures in the composition or dispersity of the precipitated particles. Here, alloy quenching "from the region of solid solutions" turns out to be an unnecessary operation. The article proposes to exclude it from the technological process, limiting itself only to tempering. This will bring large savings to all machine-building plants around the world.
