Annealing, quenching and heat treatment of tungsten
Increased interest in heat treatment of refractory metals is that they have a number of important advantages. One of the features of these materials is the dependence of their properties on the orientation of the single crystals. The technology of obtaining single crystal ribbons of single crystals of refractory metals, particularly tungsten, the method of crystallographically oriented rolling.
In modern powder metallurgy can be divided into two main areas 1) the creation of materials and products with such characteristics that cannot be achieved by known methods of melting 2) achievement of higher profitability in the manufacture of traditional materials. Heat treatment of metal powders is possible to obtain materials with unique properties. For example, tungsten, obtained in an inert atmosphere in the voltaic arc, fragile. Pressing tungsten powder and subsequent sintering in the hydrogen atmosphere is made of durable metal bars that can be forged, rolled in foil and die-cutting.
The hardening process of a hard alloy based on tungsten involves heating the alloy to a temperature above 1100 °C and cooling in a quenching medium. Commonly used aqueous solution of the polymer-based concentrate Thermovit-M with a concentration of 2−8%. The method allows to increase service durability of the material.
