The Ni-16Cr-9A1-3Fe and Fe-15.8A1-2.2Cr-0.2Zr alloys (or minor variants) can be
recommended for future hot gas filtration trials for IGCC applications (<650 C) with significant
downtime corrosion problems, but Ni-16Cr-9Al-3Fe would be preferred (due to high temperature
strength) if higher temperature excursions may be encountered. The robust performance of the
rolled and welded thin sheets of porous Ni-16Cr-9Al-3Fe in actual combustion environment
exposure tests is strong support for the hot gas filter material fabrication approach that was
developed in this project, as well as for the alloy design.
