Materials research activities have included work in the areas of coal-slag/refractory interactions, ultrasonic erosion monitoring of metals, fluid acoustics, high-temperature gaseous corrosion of metal alloys, and failure analysis. Work on coal-slag/refractory interaction has included the design of a gas-fired rotating-drum dynamic-slag corrosion test furnace. Field tests on the high-pressure loop (1 1/4-in. 321 SS piping) at the Solvent Refined Coal Liquefaction Pilot Plant were terminated because of excessive erosive wear (1.27 mm lost). Longitudinal and shear-wave velocity measurements from room temperature to 540/sup 0/C were obtained on Types 304, 304L, 316, 347, and 410 stainless steels, Fe-2 1/4Cr-1Mo steel, Stellite 6B, Haynes metal, cold-rolled steel, and cast stainless steel. Work on the fluid-acoustic test loop included changing all seals at the flange joints and calibrating the volumetric flowmeter by using an ASME orifice plate installed in the test section. Agreement within 10% was achieved. The loop has now been cycled several dozen times over a wide range of flow rates. Corrosion experiments have been conducted to evaluate the influence of combustion gas stoichiometry and deposits, such as CaSO/sub 4/, on the corrosion behavior of materials for use as air and steam heat-exchanger tubes. Analyses of failed components from the Grand Forks Energy Technology Center's Slagging Coal-gasification Pilot Plant have been completed.
