Selection and laboratory testing of Half-Heusler (HH) alloys for high-temperature TEG

Analyze and identify from an existing database of Half-Heusler (“HH”) alloys, those alloys that best fit to the GTI thermoelectric generator (“TEG”) specifications, namely: the material must be able to operate at optimal efficiency output at around 650°C; be able to handle thermal shock (thermal cycling from 15°C to 600°C in less than 30 seconds); and show low performance degradation over time (average 200 cycles per year and a useful life of 10-20 years).
