UC3Design alloys for extreme-temperature HPHE
HEA/RHEA alloys for extreme-temperature HPHE
Design high-entropy and refractory alloys for heat-pipe heat exchangers operating in oxidizing industrial gases at ≥1100°C.
Decarbonizing foundational industries requires waste-heat recovery beyond Ni-superalloy limits. TC provides industrial HPHE specifications; KTH leads CALPHAD/DFT-informed design. RHEAs developed here also enable future steel production (>1500°C) and aerospace hypersonic thermal management (e.g. additively manufactured OHPs).
