Annealing, quenching and heat treatment of tungsten

Are you interested in annealing and other types of heat treatment of tungsten and its alloys from the supplier company AvecGlob? Here you will find interesting information on this topic.

Annealing

Tungsten alloys, obtained from metal powders, necessarily undergo annealing, as a result of which the density and strength parameters acceptable for subsequent processing are obtained.

The annealing temperature is established by the properties of the structure and the influence of the capillary state of the tungsten alloy.

Tungsten alloys after deformation treatment (rolling or pressing), subject to vacuum, to obtain acceptable mechanical characteristics. The annealing temperatures range from 800 ℃ to 1450 ℃, with a holding time of 1 hour,

After low-temperature annealing at 800 ° C, the microstructures of tungsten alloys remain practically unchanged, while high-temperature annealing (at 1200 ° C) influences both the structure of the alloys and their strength. With a further increase in the heat treatment temperature (up to 1450 ℃), tungsten grains are recrystallized: the grains acquire a spherical shape that connects the main phases around tungsten particles. Conventional tungsten alloys at 1430 ℃ again go back to the initial state after sintering.

Supplier — AvekGlob company — offers at an affordable price from the manufacturer in a wide range of raw billets that are obtained from tungsten and its alloys. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Other types of heat treatment

For most tungsten alloys (especially those based on carbides), leveling annealing is often used to improve plasticity at a certain reduction in hardness. Such annealing is performed in furnaces with a controlled atmosphere, with hydrogen and oxygen restriction, predominance of inert gases. The presence of bound hydrogen in a tungsten alloy is highly undesirable, since the brittleness of the alloy is even greater. Tungsten alloys, which contain more than 30% tungsten, are not subjected to such treatment. Hardening and surface hardening for tungsten alloys is not used.

Supplier — AvekGlob Company — offers to purchase various rolled profiles, which are made of tungsten and tungsten alloys. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
