STUDIES OF TERNARY Cr-Nb-Mo ALLOY AT CHROMIUM AND NIOBIUM ANGLE (in Russian)
Melting point, macro- and microstructure, and partial x-ray diffraction studies were made of the ternary Cr - Nb Mo alloy. The microstructure showed that the ternary alpha solid solution of chromiun, niobium, and molybdenum was found in the chromiun and niobium corner. The region expands with the increase of molybdenum. A large two-phase region of Cr/sub 2/Nb and ternary alpha solid solution is adjacent to chromium - niobium side. The boundary was found for the Cr/sub 2/Nb two-phase region and alpha solid solution for 1500 to 100 deg C. The x-ray studies uncovered the ternary solid solution of Cr, Nb, Mo, and Cr/sub 2/Nb compounds. The microhardness of the alloys indicates two phases differing in microhardness, the Cr/sub 2/Nb compound with 1200 to 1850 kg/mm/sup 2/ and ternary alpha solid solution with 250 to 700 kg/mm/sup 2/.
