Rare, refractory metals and alloys
In the group of rare metals included whiter than fifty elements. The main feature of them is little known and rare usage in the industry. Modern industry finds adequate to use a few of them.
Refractory metals
Their appearance came on the market recently. Vanadium, tungsten, molybdenum, rhenium, etc. began to be actively used in the first third of the last century. Experienced by the leading metallurgists of that time were developed the technological schemes of production and application of refractory metals. Today there is a trend of broadening the uses of these elements, in particular for alloying heat-resistant alloys or for independent use. When using certain technologies such as powder metallurgy, which developed by leading experts in the industry, it is possible to obtain materials with exceptional properties.
Production
For smelting of rare refractory metals, used smelting equipment, designed for the highest temperature. Getting them regulated by the appropriate documentation, which stipulated the basic requirements for the production process: melting, molding, machining.
Application
Such metals are introduced into the composition of alloys in small quantities for the production of critical heat-resistant products. Of them are made indispensable in the nuclear power industry, electrical engineering, electronics, military materials, uncontested in its field. Refractory metals has found its use in alloys in corrosive environments, in the processing of other metals exploration at the percussion-rotary drilling, thermometry metallurgical processes, etc. it is Justly considered that refractory metals are endowed with extraordinary qualities among metals having a standard set of characteristics. Their high resistance to corrosion of the plan are unparalleled. In heat resistance they are second only to carbon. Therefore, the metals of tungsten is indispensable for the welding arc type as a consumable electrode or as a filler component. Molybdenum is used in the manufacturing process of the reed relay type. In water supply systems have found application alloy stainless steel grade, comprising chrome or Nickel. The interaction of these two components gives excellent results in terms of corrosion resistance.
The main indicative feature of any metal is its belonging to a certain group in the periodic table that allows you to competently carry out selection of compatible elements in the alloy. This significantly eases the task associated with making certain alloys of improved properties. The lanthanides are used for the production of complex mechanisms used in mechanical engineering and electrical engineering. In electrical engineering the lanthanides stabilize the alloy to the effects of harmful factors and acidic environments. This point is very significant, as it has a great importance in the manufacture of, for example, welding electrodes.
