ANP PROJECT PROGRESS REPORT THERMAL-CONVECTION LOOP TESTS OF INCONEL CASTINGS J. H. Devon E. A. Kovacevich In order to evaluate the use of lnconel castings for large, intricate sections required in the ART, three standard inconel thermal-convection loops with cast lnconel inserts in the hot legs were operated for 500 hr. The castings, whose compo- sitions are given in Table 3.1.3, contained approxi- mately 1.2% manganese, 2% niobium, and 1 to 2% silicon. Inserts 321 and 322, which had the lowest and the highest silicon contents, re- spectively, were tested in loops which circulated the fuel mixture (No. 30) NaF-ZrF4-UF, (50-46-4 mole %) at 150O0F, while the remaining insert, 323, with an intermediate silicon content, was 136 tested in a loop which circulated sodium at cd 15OOOF. . As shown in Table 3.?.4, very severe corrosion of the cast specimens was found in the loops which circulated the fuel mixture. The attack occurred not only in the form of the subsurface voids that are typical of the attack of wrought Inconel, but, in addition, very deep intergranular penetrations appeared, which reached in the worst case to a depth of 70 mils, as shown in Fig. 3.1.3. These intergranular penetrations, although a result of rapid attack of grain-boundary con- stituents, were aided considerably by the porosity and the shrinkage cracks present in all the castings in the as-received condition, as shown in Fig. 3.1.4. The casting containing 1% silicon was found to be TABLE 3.1.3.
