An Alloy That Laughs at 1300 Degrees
A turbine blade in a jet engine glows white-hot. Conventional nickel-based superalloys start to fail at 1200 °C: their strength melts away like butter in a skillet. Yet future turbines need to run even hotter to burn fuel more efficiently.
Engineers have proposed a new composition: niobium, tantalum, titanium, and vanadium, mixed in unequal proportions.
