Creep-rupture behavior of iron superalloys in high-pressure hydrogen
Technical Report
·
OSTI ID:5619603
The creep-rupture properties of five iron-base and one cobalt-base high-temperature alloys were investigated to assess the feasibility of using the alloys as construction materials in a Stirling engine. The alloys were heat treated and hardness measurements were taken. Typical microstructures of the alloys are shown. The creep-rupture properties of the alloys were determined at 760 and 815 C in 15.0 MPa H2 for 200 to 1000 hours. Plots of rupture life versus stress for the six superalloys are presented along with creep strain-time plots.
