“…The role of the c 0 phase has since been confirmed by a number of researchers. [6,[12][13][14][15] But what happens in the absence of the c 0 phase? Alloys containing very few or no c 0 -forming elements have also been shown to form serrated grain boundaries, for example Haynes 230, Inconel 690, Inconel 617, and Nimonic 263.…”

Grain boundary serration in the superalloy Inconel 600 was studied. Two microstructural variants, one with nonserrated and the other with serrated grain boundaries were generated by altering the heat-treatment conditions, while keeping other aspects of the microstructure unchanged. The effect on the creep response between 700°C and 900°C was measured, and the different failure modes and accumulated damage were quantified using high-angular resolution electron backscatter diffraction analysis in the scanning electron microscope and also by X-ray computed tomography. It is found that serration plays a more crucial role in the high-temperature/low-stress regime when an intergranular cracking mechanism involving cavitation is operative; here it plays a role in improving both creep life and creep ductility. Any effect of serration is less prevalent at low temperatures where transgranular failure is dominant.

“…), which is confusing. The atomic radius of pure metals (Ni, Co, Fe) [3] and the lattice parameters for these metals as well as chromium carbides (Cr 7 C 3 , Cr 3 C 2 , Cr 23 C 6 ) [4,5] are shown in Table 2. It is evident that 2.8681 and 2.857Å cannot be the atomic radius and are not even close to any lattice parameters of the possible phases present in Stellite alloy, alloys Inconel 600 or Inconel I-82.…”
