The increased interest in heat treatment of refractory metals is related to the fact that they possess a number of important advantages. One of the features of these materials is the dependence of their properties on the orientation of single crystals. The developed technology of obtaining monocrystalline ribbons from single crystals of refractory metals, in particular tungsten, by crystallographically oriented rolling.

Powder metallurgy

There are two main directions in modern powder metallurgy 1) creation of materials and articles with such characteristics that are impossible to achieve by the known methods of melting 2) achievement of higher profitability in manufacturing traditional materials. Heat treatment of metal powders can produce materials with unique properties. For example, tungsten produced in an inert atmosphere in a volt arc is brittle. Pressing tungsten powder and subsequent sintering in a hydrogen atmosphere produces strong metal bars that can be forged, rolled into foil, and stamped.

Quenching

The method of hardening tungsten-based carbide involves heating the alloy to a temperature above 1,100 °C and cooling it in a quenching medium. Typically, an aqueous polymer solution based on Termovit-M concentrate with a concentration of 2-8% is used. The method allows to increase the service resistance of the material.
