High-temperature alloys or superalloys are another challenge. They contain chromium for oxidation resistance and elements like aluminum, vanadium, tantalum, niobium, titanium, zirconium, hafnium, and other elements added as gamma prime formers, which strengthen the matrix of the materials by the precipitation of the gamma prime intermetallic compounds that are stable at high temperatures.
Hydrogen would form hydrides in case of tantalum, niobium, titanium, zirconium and hafnium and cause hydrogen embrittlement in superalloys.
Carbon is also not desired in these materials as the carbides would reduce the amount of gamma prime precipitates. Oxides of aluminum, titanium, zirconium, and hafnium cannot be reduced by either carbon or hydrogen. Vacuum or argon is the atmosphere of choice in most cases.

Heat resistance applications typically require consistent performance at temperatures over 1200°F (649°C).
Alloys with high performance levels of oxidation resistance, creep strength, stress rupture life, and tensile strength contribute to heat resistance properties.
Heat-resistant metals are found in many different industries including:
Automotive Aerospace Aviation Ceramic Chemical
Construction Electronics Glass Machine Shops Military Petrochemical
