With the rapid development of aerospace technology, the engine system requires the thrust chamber to be lightweight and able to adapt to the aerodynamic heating effect of rarefied flows in…

With the advancement and development of aerospace technology, the requirements for engine performance (such as combustion efficiency, payload, and on-orbit operating life) continue to increase, which requires further improvement of…

Niobium alloys are usually divided into 6 categories according to their strength grades and functional properties: the first category of high-strength and low-plasticity niobium alloys, the second category of medium-strength…

In the late 1950s, people developed a strong interest in nuclear power, aviation and space flight, and began to develop related niobium alloys. Since the 1960s, the development of commercial…

Niobium alloys used for high-temperature structural parts are mainly divided into four categories: high-strength niobium alloys, medium-strength niobium alloys, low-strength niobium alloys and low-density niobium alloys. The strengthening methods of…

Due to limitations in operating temperature and high-temperature mechanical properties, C-103 alloy and niobium silicide anti-oxidation coatings have been unable to meet the evolving needs of spacecraft. To this end,…

C-103 (Nb-10Hf-1Ti) alloy is a low-strength niobium alloy with good high-temperature strength, excellent formability and welding performance. It is widely used in rocket thrusters and other fields. It is an…

Compared with other types of superalloys, high-temperature niobium alloys have the advantages of low density, high-temperature (600-1600°C) specific strength, excellent cold and hot formability and good welding performance, and can…

The most direct feature of the vanadium battery (all-vanadium redox flow battery) is its structure: it is composed of two solution tanks (electrolyte using two kinds of vanadium ions with…

Vanadium is a silver-gray metal. The melting point is 1919±2°C, which belongs to the list of rare metals with high melting point. The boiling point of metal vanadium is 3000--3400°C,…
