Nonequilibrium segregation and boundary defects in heating alloys to high temperatures

Conclusion

As a result of steels and alloy being heated to high temperatures, the following defects may arise in the structure:

  • - nonequilibrium segregation of the alloying elements distinguished by high binding energy between atoms and vacancies;

  • - accumulations of vacancies attaining the size of micropores.

Nonequilibrium segregation and microdamage of the grain boundaries reduce cold and hot plasticity, resistance to general corrosion, and they increase the proneness to intercrystalline failure. In addition to that, they facilitate the nucleation and growth of excess phases along the grain boundaries.
