High-temperature ordered intermetallic alloys

WebNov 29, 2013 · Since Ni 3 Al melts at 1395°C and Ni at 1453°C, it is clear that significantly higher operating temperatures, with the attendant improvements in efficiency and thrust-to-weight ratio, can only be attained by the development of an entirely new materials system. WebUnlike most alloys, IC-221M increases in strength from room temperature up to 800 °C. The alloy is very resistant to heat and corrosion, and finds use in heat-treating furnaces and other applications where its longer lifespan and reduced corrosion give it an advantage over stainless steel.
