Hostile environmental conditions facing candidate alloys for the automotive Stirling engine
Abstract
A materials research program is underway at NASA Lewis Research Center in support of the DOE/NASA Automotive Stirling Engine Project. The program focuses on the hot heater head of the engine including the heater head tubes, cylinders, and regenerator housings, which are considered to be the most critical components from a materials viewpoint. The specific areas of investigation in the progam involve hydrogen permeability testing, doping of the hydrogen working fluid to reduce permeability rates, oxidation/corrosion studies, creep-rupture evaluation, and assessing effects of hydrogen environment on mechanical properties. Recent results in each of the aforementioned areas of research are described. Special emphasis is placed on the materials challenges that result from the use of hydrogen as the working fluid in this potential alternative engine to today's internal combustion engines.
