Niobium alloy, which is a new high-end material, melting point more than 2400 degrees Celsius, can not be refined on Earth, can only be sent to space microgravity environment to make it.
Niobium alloy is a niobium based alloy formed by adding several elements. Generally speaking, the properties of the alloy are relatively excellent, and the melting point exceeds 2400 degrees Celsius. Such high temperature resistant materials, people often think of the first time is such a hard metal like tungsten, but niobium alloy can withstand high temperatures at the same time, but also has a strong toughness. Speaking of this, we have to talk about the history of human discovery of niobium metal. The history of human discovery of niobium metal goes back to 1801. That year, British chemist Charles Hatchett discovered niobium in a sample of an ore in the British Museum. The sample was sent by John Winthrop of Connecticut in 1734. It was not until 1949, when the International Society of Pure and Applied Chemistry held a meeting and made a ruling, that the name of element 41 in the periodic table was officially determined to be "niobium", and "columbium" was retained as the old name. This is the end of a long naming controversy.
In fact, materials such as niobium alloy with high temperature resistance are usually prioritized for use in the aerospace industry, especially spacecraft engines, which not only require high temperature resistance of materials, but also high strength of materials. Like the traditional use of ceramics, although the high temperature resistance to meet the requirements, but this material at room temperature will produce brittleness, always unsatisfactory. Niobium thermal strength alloy has good thermal strength, thermal resistance and processing properties, just meet the needs of aerospace engines, the most suitable for the manufacture of engine parts, as well as gas turbine blades.
In the future, it can not only be assembled on aerospace equipment, but also ensure that the performance of the blades created by it is very stable at room temperature and high temperature, and also ensure the internal hollow, so that the gas in various internal pipelines can achieve smooth circulation and good heat dissipation effect.
