Effects of different elevated temperature and long-term exposure on microstructural evolution and mechanical characteristics of IN617 Ni-based superalloy

Effect of Ta on solidification characteristics and mechanical properties of DZ411 Ni-based superalloy

“…Thus, it is necessary to further clarify the effect of Ta content on dendrite arm spacing of superalloys. Furthermore, although the effect of Ta addition on solidified microstructure and mechanical properties of the Ni-based superalloy have been reported in previous studies [23][24][25] , there are limited investigations on Ta addition and its effect on microstructure evolution and microhardness in both the primary dendrite and interdendritic regions of the directionally solidified Ni-based superalloy.…”
