HybriTherm™

Thermally Engineered Alloys

HybriTherm™ is a highly thermally conducting, high temperature, syntactic metal composite alloy. HybriTherm combines the thermal conductivity of graphite with the mechanical properties and fabricability of metals. As a result of it’s unique structure, HybriTherm has 3-5X the thermal conductivity and 30-70% lower density and modulus compared to traditional nickel and iron based superalloys. This combination of properties results in reduced weight, reduced peak temperatures, and tremendous resistance to thermally induced buckling loads and thermal shock encountered in high temperature environments.

A >70% reduction in thermally driven stress is readily achieved using HybriTherm materials. Due to this unique combination of properties, HybriTherm high conductivity syntactic metal composites provide solutions to problems with manufacturing, reliability, and performance of highly thermally stressed structures, such as hypersonic vehicles, cooled engine structures, and thermal energy storage systems. Thermally engineered HybriTherm structures provides designers added degrees of freedom to manage thermal stresses, high heat loads, and localized heating while reducing weight and cost.

HybriTherm composite alloys can be fabricated from a range of metals, including titanium, iron-, and nickel- based superalloys for temperatures of 650-1350C, and niobium, molybdenum, and other refractory metal alloys for temperatures of 1300-1700C+.

HybriTherm metal composites exhibit (compared to metals)

In hot structure applications, these properties lead to:

These features result in performance improvements, including:

HybriTherm can be fabricated in traditional metal forms, including isogrid, L-stiffened panels, plate, rod, tube, and sheet form. It can be generally be formed similar to metals, and is easily machined, bolted, threaded, brazed, and can even be welded for assembly. Depending on the alloy, wrought, rolled, and extruded product can be readily produced, or net shape powder metallurgy or cast shapes can be produced.
