The studied alloy is GH99 alloy,which is a kind of nickel-based superalloy with low stacking fault energy,and it has been widely used in combustion systems,gas turbines and other related high temperature applications due to its excellent high-temperature strength,creep resistance and corrosion resistance.In addition,theγ′phase(Ni3Al Ti)is the main strengthening phase for GH99 alloy,and the highest working temperature of such alloy can reach around 1000oC[21].The chemical composition(wt%)of the alloy used in this investigation is listed in Table 1.
