| Summary: | Title screen This paper presents transmission and scanning electronic microscope investigations of Ni-Al-Cr superalloy alloyed with additional Re and La elements. This superalloy is obtained by the directional solidification method and subsequently is subjected to two-stage high-temperature annealing: 1) at T = 1150°C, the test time is 1 hour; 2) at T = 1100°C, the testing time is 1430 hours. It was found that the ?- and ?'-phases are the main phases in the two states on the basis of fcc lattice. Where ? is the disordered fcc solid solution and ?'-phase is the main phase with an ordered arrangement of atoms having the L12 superstructure. It is shown that such additional elements as Re and La result in the formation of new phases in Ni-Al-Cr accompanied by considerable modifications of quasi-cuboid structure in its ?'-phase. The phase composition and morphology of the phases are studied. Режим доступа: по договору с организацией-держателем ресурса |
