Niobium alloy is made by adding appropriate elements and using vacuum arc remelting. The most common metal filler.The additives are zirconium, thallium and hafnium, which are.
Niobium solution is added during arc melting. Properties of commercial Niobium alloys High temperature niobium alloys are mainly enhanced by solid solution reinforcement and exist in the alloys.
A small number of second phase particles. The composition of grains is different, but it is generally related to the intercalation impurities that make up oxides, nitride and carbonates. Because of the second phase.
The size and distribution of the alloy are often on mechanical properties and recrystallization have a great influence, so these particles are very important. In general, niobium alloys are much less resistant to impurities than other active metals such as titanium and zirconium. Contain in grain.
The second phase forming a continuous grain boundary microparticle alloy greatly reduces the tensile elongation. This can occur during contamination and improper heat treatment. In the welding. You might accidentally add copper to the process, Will have adverse effects on the mechanical properties of the alloy. The allowable amounts of oxygen, hydrogen, carbon, and nitrogen in niobium are titanium or zirconium.
All commercial alloys exhibit good ductility at room temperature. Wc-3009 alloys have the most at room temperature and elevated temperatures. High tensile strength. FS–85. Gold has super creep strength. This is due to its high melting point which increases with the concentration of thallium and tungsten.
Manufacturing of parts currently, commercial alloy suppliers cast the alloy into ingots, for example, to facilitate the winding of circular plates. A circle or form used in the manufacture of pipes cone. The parts are prepared by high temperature extrusion and forging when they are close to the recrystallization temperature of the alloy. The general temperature is 1000-1300℃.
