Questek Innovations has been awarded three small business research projects to design and develop alloys for the US government.

The alloys will help address energy, aerospace, environmental and operational needs for the US Department of Energy and the Office of Naval Research.

The nine-month programme will see Questek develop new alloys for coal-fired power plants with steam temperatures of 760°C. It will develop prototype ingots to test creep strength, thermal fatigue, oxidation resistance and other properties.

Increasing the steam temperature of advanced ultra-supercritical boilers can raise the operating efficiency of next-generation coal-fired power plants and address environmental issues.
