The vast majority of single rare earth metals and their intermediate alloys are used to produce new rare earth metal materials such as neodymium iron boron, samarium cobalt permanent magnet and super magnetostriction and non-ferrous metal alloys such as AI-RE, Mg-RE, Cu-RE, Zn- RE, W-RE, Mo-RE, etc. In addition, there are a few rare earth metal applications that use some special properties to prepare functional materials. Neodymium metal, praseodymium and praseodymium neodymium alloy Neodymium has the hard-magnetic properties caused by the good 4f electron spin arrangement, and has become the largest user of neodymium iron boron permanent magnet materials. In recent years, the global neodymium iron boron materials have developed rapidly, and the large application of neodymium metal in neodymium iron boron permanent magnet materials has driven the rapid development of the rare earth industry. In addition, neodymium metal as an alloy additive has good purification, modification and alloy...

Although many nitinol applications are not well-known to the public, some applications are quite routine and familiar. The spectacle frame made of Nitinol severely deformed and then returned to normal. Similarly, a few years ago, when mobile phone antennas were made of Nitinol, they could bend without breaking or permanently bending. Another superelastic application of Nitinol is for orthodontic archwires. The orthodontist uses fixed nitinol wire to fix the teeth. Since the wire is super-elastic, it will try to restore its straight state and continue to exert force on the teeth. This can reduce frequent visits to orthodontists to tighten braces. Many little-known applications use Nitinol's shape memory function. A well-known computer manufacturer used Nitinol equipment to eject PCMCIA cards. In addition, Nitinol is also used to connect the end of the aircraft hydraulic tubing. Nitinol can make the magic shop spoon bend in hot water also because of its shape memory function Nitinol...

Rare earth metals have typical metal properties. They have strong chemical activity and can form a variety of compounds, including hydrides, chlorides, silicides, carbides, organic / inorganic salts and complexes. This is the basis for the rare earth metal in the metallurgical industry as a purification, impurity removal and refinement modifier. Rare earth metals are unstable in air, and their stability increases with increasing atomic number; in other words, the rare earth metals with larger atomic radius have weaker oxidation resistance; light rare earth metals can be easier oxidized than heavy rare earth metals, and lanthanum is the most active. Lutetium and Scandium are the most resistant to air oxidation. Rare earth metals are widely used as reducing agents, which can reduce oxides of iron, cobalt, nickel, chromium, vanadium, niobium, tantalum, zirconium, titanium, silicon and other elements into metals. Due to the difference in the reducing ability of rare earth metals, and the ...

The finished products of niobium and niobium alloy materials and their processing and preparation processes need to be annealed and heat treated. The heat treatment methods include homogenization heat treatment, stress relief heat treatment, recrystallization heat treatment and mechanical heat treatment. -Homogenization heat treatment. The homogenization heat treatment is to eliminate defects such as metastable phases and component segregation in the ingot by atomic diffusion, and to make the structure uniform and stable. The homogenization temperature of the niobium ingot is 1800~2000 ℃, the vacuum degree is 10-2~10-3Pa, and the holding time is 5-10h. -Stress-relief heat treatment. The purpose of stress-relief annealing is to eliminate or reduce the internal stress of the material and improve the mechanical and technological performance of the material. Therefore, at a given temperature, the stress and strain energy can be eliminated quickly. -Recrystallization heat treatment. The re...
