In the tungsten-rhenium alloy, the addition of rhenium can not only improve the strength of the material, increase the recrystallization temperature of the alloy by about 200~400 ℃, make the secondary recrystallization good plasticity and slow grain growth, but also significantly reduce the plastic-brittle transition temperature. Addition of more than 30% of rhenium impairs the workability of the alloy. Tungsten rhenium alloy also has a high thermoelectric potential, at 2200 degrees Celsius, the thermoelectric potential and temperature into a linear relationship. Tungsten rhenium thermocouple measuring temperature can be as high as 3000 ℃, is excellent high temperatureThermocouple Materials.

The main problems of China's cemented carbide industry:

First, the scale of enterprises is small and the industrial concentration is not high.

Second, less investment in science and technology, lack of high-end technical personnel, technology research and development capacity is weak. China's cemented carbide industry in science and technology investment is less than 3% of sales revenue, the level of scientific and technological research and development is not high, the original core technology achievements are less.

Third, the product quality level is low, and the product structure needs to be adjusted. China's cemented carbide production accounts for more than 40% of the world's total output, but the sales revenue of cemented carbide is less than 20% of the world's total, mainly due to the low output of high-performance ultrafine alloys, high-precision and high-performance abrasive coating blades, superhard tool materials, complex and large products, precision cemented carbide CNC tools and other high value-added products, insufficient deep processing and incomplete varieties.
