Comparison Of Heat Resistance Between Tantalum And Niobium Sheet

2024-01-05 18:00:06

Compared with niobium plate, tantalum sheet containing plate has superior performance, higher heat resistance and greater stress load. But the base heat - resistant alloy is mainly divided into TaW and TaNb two series, other additives have molybdenum, hafnium, rhenium.

These alloys have excellent properties, such as high temperature strength (1650℃ or higher) and creep resistance, good low temperature plasticity and welding properties. These alloys are mainly used as heat-resistant and high-strength structural materials for supersonic aircraft, solid propellant rockets and missiles, as well as parts for control and regulating devices. For example, the combustion chamber of agina spacecraft is made of TA-10W alloy, and its combustion chamber flame temperature is very high (up to 2,760 ℃).
