You don't know the world of steel niobium alloy

Firmetal, 2019-06-18 09:43:00 PM

From the mid-1950s to the early 1960s, niobium alloys with excellent oxidation resistance and high strength were mainly developed. Later, niobium alloys with good processing and welding properties were developed, and the research of niobium alloy antioxidation protective coating was strengthened. China began the niobium production process research in 1958, and began the industrial production of niobium in 1963.

As the raw material of C103 alloy, niobium - tantalum - tungsten alloy bar has strict requirements on Ta, W and gas impurities C and O. The process of producing nb-ta-w alloy bar by powder metallurgy is studied in this paper. The method of uniform distribution of Ta and W was found out, and a reasonable process scheme was put forward.

Study on superconductivity of niobium titanium alloy under ultra-high pressure

Firmetal, 2019-06-13 09:12:00 PM

Niob-ti alloy superconductor has been widely used in thousands of known superconductors because of its excellent comprehensive properties. Niobium titanium alloy is a typical binary alloy composed of transition group elements. In the previous study on the high-entropy alloy superconductor (TaNb)0.67(HfZrTi)0.33 composed of multi-element transition group metal elements, it was found that the alloy showed unusually stable superconductivity under ultra-high pressure (pressure over one million atmospheres is ultra-high pressure, and 1 million atmospheres =100 GPa). Since niobium and titanium are the main components of this high entropy alloy, the research on the superconductivity of niobium and titanium alloy under ultra-high pressure can deepen the understanding of the microscopic mechanism of superconductivity of high entropy alloy.

Research status of corrosion resistant coating on zirconium alloy surface

Firmetal, 2019-06-12 09:32:00 PM

Thermal barrier coating is a layer of ceramic coating, which is deposited on the surface of high-temperature resistant metal or super alloy. Thermal barrier coating plays a heat insulation effect on the substrate material and reduces the temperature of the substrate, so the device made can operate at high temperature.
