Next、 I will briefly introduce the testing standards and process of Baijia.net for tungsten rhenium alloy testing
Tungsten rhenium alloy is a solid solution strengthened alloy composed of tungsten element as the matrix and rhenium element. The commonly used rhenium content (mass fraction、%) in alloys is 3、 5、 10、 25、 and 26. Divide into low content W-Re alloys (Re ≤ 5%) and high content W-Re alloys (Re ≥ 15%)
Tungsten and rhenium are both high melting point metals、 and they are widely used in high-temperature fields. But they also have drawbacks: pure tungsten is brittle and the recrystallization temperature is very low; Pure rhenium has poor processing performance and is expensive. Their application scope is greatly limited. Tungsten and rhenium are made into various components of tungsten rhenium alloys、 which overcome the shortcomings of pure tungsten and rhenium and have many excellent properties、 such as high melting point、 high strength、 high hardness、 high plasticity、 high resistivity、 high recrystallization temperature、 high thermoelectric potential value、 low vapor pressure、 low electron escape work、 and low plastic brittle transition temperature、 At the same time、 they also have excellent resistance to water circulation The reaction performance and price are also 75-95% lower than pure rhenium.
Therefore、 tungsten rhenium alloys have been widely used in electronic technology、 thermal control、 modern nuclear technology and space navigation technology、 temperature measurement fields、 instruments and meters、 electrical appliances、 and other cutting-edge scientific and technological departments. Especially when tungsten rhenium alloy wires are matched with thermocouples、 they have high thermoelectric potential and sensitivity、 and have a wide temperature measurement range、 fast reaction speed、 and good corrosion resistance、 It is a good thermal sensing material in the field of temperature measurement. Due to the trend of tungsten rhenium thermocouples replacing platinum rhodium thermocouples
