Phase transformations during heating of cast and deformed alloy KhN62BMKTYu

  • 16 Accesses

Conclusions

The sharp reduction of the fracture toughness of nickel alloys at temperatures exceeding the temperature at which the basic hardening γ′ phase goes into solution is due to the formation of micropores in the boundaries of micrograins in interaxial sections of dendrites of the cast alloy or in the grain boundaries of the deformed alloy. Further reduction of the fracture toughness is evidently due to melting of the grain boundaries.
