The results of the EDS analysis at point A in Fig.9(a)and the distribution of the Nb,Ti,and W elements are presented in Table 4 and Fig.9,respectively.These results clearly demonstrate that this crack forms because of the melting of an MC-type carbide that is rich in tungsten,titanium,and niobium(Fig.9).These results demonstrate the destructive role of grain-boundary strengthening phases(e.g.,MC-rich carbides of tungsten and niobium)in the welding of Zh S6U superalloys.
