Candidate iron-base alloys for heater tube application in the stirling automotive engine were aged at 760/sup 0/c for 3500 h in a low pressure argon or hydrogen atmosphere to determine the effect on mechanical behavior. The seven alloys evaluated were n-155, 19-9dl, 316ss, nitronic 40, a286, incoloy 800h, and ra330.
A stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas (the working fluid) at different temperatures, such that there is a net conversion of heat energy to mechanical work. More specifically, the stirling engine is a closed-cycle regenerative heat engine with a permanently gaseous working fluid.
