1920 Concrete May 72/2 It is possible to make a super-cement by adding ingredients to the raw material, just as it is possible to make super-alloy steels with special ingredients and treatment of the steel.
1953 C. L. Clark High-temp. Alloys xvi. 269 Up to the time of the introduction of these superalloys it was generally agreed that any alloy intended for high-temperature service should be processed and heat treated.
1981 McGraw-Hill Yearbk. Sci. & Technol. 325/1 Superalloys can operate for extended periods of time at temperatures about 1200°F (650° C), and provide resistance to hot corrosion and erosion.
2001 R. W. Cahn Coming of Materials Sci. ix. 355 The best superalloys now operate successfully at a Kelvin temperature which is as much as 85% of the melting temperature.
