Effect of microstructure on fatigue crack propagation in additive manufactured nickel-based superalloy Haynes 282: an experiment and crystal plasticity study

Microstructure sensitive fatigue life prediction model for SLM fabricated Hastelloy-X

“…The application of crystal plasticity models to investigate the effect of the resulting microstructures of AM metals in their fatigue performance is a trending topic nowadays. These models have already been applied to some SLM fabricated superalloys [45,46,47,48]. In some cases the life prediction is focused on crack propagation [47] stage.…”

“…These models have already been applied to some SLM fabricated superalloys [45,46,47,48]. In some cases the life prediction is focused on crack propagation [47] stage. Other studies consider crack nucleation but the life prediction model is directly linked with the macroscopic cyclic response [25,20,27], without making use of the distribution of microscopic fields obtained.…”

The Impact of Plastic Deformation on the Microstructure and Tensile Strength of Haynes 282 Nickel Superalloy Produced by DMLS and Casting

“…A number of recent studies on the AM technique have focused on the production of nickel superalloys [ 4 , 6 , 7 ], including Haynes 282 superalloy [ 2 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ].…”

“…The authors of studies [ 11 , 12 , 13 , 14 , 16 , 17 ] also conducted research on the Haynes 282 alloy produced using PBF technology. Shaikh et al [ 12 ] focused on the mechanical and microstructural studies of the alloy.…”

“…Paper [ 14 ] looks at the fatigue crack growth behavior of Haynes 282 produced by PBF. Using numerical simulations, the authors showed the influence of grain structure and texture on crack propagation.…”
