文摘
- •
Finite element models were built based on crystal plasticity theory.
- •
Anisotropic grains were simulated and intercrystalline interactions were analyzed.
- •
Stress concentrations caused by micropores shortened the fatigue life of the alloy.
- •
HIP treatment reduced the plastic deformation and extended the alloy fatigue life.
- •
Microstructure can be optimized with the help of HIP treatment.
