How to control the quality of refractory metal materials? With the progress of technology and the complexity of market demand, the quality requirements of refractory metal materials are getting higher and higher. Only by continuously improving the quality of refractory metal materials, can greater economic and social benefits be achieved.

  1. Optimizing the Composition of Materials

  The optimization of material composition is mainly achieved by alloying and doping. This method can improve the quality and properties of refractory metal materials.Making tungsten and rhenium alloys into tungsten-rhenium alloys can improve the properties of materials and make them have the advantages of both materials. This alloy has high melting point, higher strength and recrystallization temperature than tungsten, while the transition temperature of ductility and brittleness is lower than tungsten. It also has good welding performance, corrosion resistance, high resistivity, low electron escape power, and has been widely used in the field of electronics.

   2. Improvement of Manufacturing Technology

   One of the effective ways to improve the quality of refractory metal materials is to improve the manufacturing process.TZM is a kind of molybdenum which has a wide range of applications and a large amount of usage. Its use environment is mainly in the high temperature situation of over 1000 degrees Celsius. However, TZM is a brittle material, it is difficult to process it by hot deformation. If direct forging is used, the yield of finished products is very low, so improving the manufacturing process becomes an effective way.

   3. Improvement of Production Equipment

  One of the important methods to improve the quality of refractory metal materials is the improvement of production equipment.In order to improve the production quality of tungsten-molybdenum wires, a large number of new equipment have been developed successfully, such as four-mode, six-mode, eight-mode multi-mode fine drawing equipment, etc. The popularization and use of these equipment can improve the quality of tungsten-molybdenum wires.

   4. Development of New Products

  With the advancement of technology and the change of market demand, the diversity and high performance of refractory metal materials have been put forward higher and newer requirements. Integrated circuits are developing towards large scale, which requires different composition, characteristics and specifications of sputtering targets. Tungsten silicide sintered by powder metallurgy in cold and vacuum environments has low resistivity, high purity and high density at the same time, which is suitable for use in MOS integrated circuits. With the rapid development of nuclear power industry worldwide, zirconium alloy pipes with variable cross-section are needed for the control rod guide pipes used in fuel assemblies. This market demand can promote the development of new products.
