Objective is to evaluate the mechanical properties of liquefaction process plant dissolver vessel materials in a coal slurry-hydrogen environment. During this period, the following were studied: fatigue crack growth rates in 2-1/4Cr-1Mo steel; thermal expansion coefficients of A387, 316 SS, and 883 steels; tensile properties of 2-1/4Cr-1Mo steel after exposure to 4000 psig H/sub 2/ at 1000 or 950/sup 0/F; corrosion of 2-1/4Cr-1Mo steel by coal slurry-H/sub 2/ at 800/sup 0/F and 4000 psig; analysis of coal and coal oil; and phase stability diagrams of Fe, Cr, Mo, and Mn in H/sub 2/S-H/sub 2/-C-O.
