Creep and creep damage behavior of stainless steel 316L manufactured by laser powder bed fusion

L. A. Avila Calderon et al.

Summary: The study demonstrates that the creep properties of LPBF 316L exhibit low defect population and more extensive creep damage, primarily manifested as intergranular creep damage. Compared to conventionally manufactured 316L, LPBF 316L shows inferior creep performance.

Strengthening mechanisms in selective laser melted 316L stainless steel

Siqi Chen et al.

Summary: The microstructure and chemical composition of 316L stainless steel prepared by selective laser melting were characterized. The study showed the presence of a multi-scale microstructure with equiaxed and columnar grains, dislocation cell blocks, individual dislocations, and nanosized particles. The misorientations across dislocation cells were determined, and the distribution of alloying elements and nitrogen content was also observed. The study found that dislocation strengthening and solid solution strengthening were the main contributing factors to the yield strength of the material.

Superior low cycle fatigue property from cell structures in additively manufactured 316L stainless steel

Luqing Cui et al.

Summary: This study investigates the influence of microstructure characteristics on low cycle fatigue properties and strengthening effects in additively manufactured stainless steel. It reveals that the presence of cell structures significantly increases the fatigue life by inhibiting dislocation propagation and promoting the formation of nanotwins. Additionally, compositional micro-segregation serves as another important strengthening mechanism. The findings highlight the potential of additive manufacturing in designing high-performance energy absorbent alloys through tailored microstructure.

Deformation mechanisms of selective laser melted 316L austenitic stainless steel in high temperature low cycle fatigue

Yefeng Chen et al.

Summary: By conducting low cycle fatigue (LCF) tests on SLM 316L and traditional 316L, it has been found that SLM 316L exhibits stable cyclic softening behavior and higher fatigue life compared to traditional 316L. This is attributed to its higher strength as well as the coarsening of cellular sub-structure, evolution of geometrically necessary dislocations (GND), and influence of texture direction.

Constitutive model for thermomechanical fatigue conditions of an additively manufactured combustor alloy

Thomas Lindstrom et al.

Summary: This study investigates and models the mechanical response of an additively manufactured nickel-based combustor alloy subjected to thermomechanical fatigue (TMF) loadings. The study found that the orientation of the material affects its mechanical properties. A constitutive model is developed to accurately describe the material's response under TMF conditions.

The effect of dwell on thermomechanical fatigue in superaustenitic steel Sanicro 25

Roman Petras et al.

Summary: The superaustenitic steel Sanicro 25 was subjected to out-of-phase thermomechanical fatigue cycles with dwell at peak temperature within the range of 250°C to 700°C. The effects of dwell on cyclic response, internal structure, and damage mechanism were studied, evaluating cyclic hardening/softening curves, stress-strain curves, and fatigue life curves. Various advanced microscopy techniques were used to analyze internal structure, nanoparticle obstacles for dislocation motion, and mechanisms responsible for fatigue crack nucleation and propagation. Discussions were made on the effects of dwells in in-phase and out-of-phase cycling on fatigue behavior, internal structure modification, and damage mechanisms.

Revealing relationships between microstructure and hardening nature of additively manufactured 316L stainless steel

Luqing Cui et al.

Summary: The relationship between microstructures and hardening nature of laser powder bed fused (L-PBF) 316 L stainless steel has been studied, showing that the hardness of the alloy is predominantly governed by GNDs. During annealing treatments, the migration of GNDs and the decrease of SSD density play important roles in the hardness variation of the material.

Fatigue behavior of Ti6Al4V alloy components manufactured by selective laser melting subjected to hot isostatic pressing and residual stress relief

J. S. Jesus et al.

Summary: The study found that the hot isostatic pressing process caused microstructural transformation in Ti6Al4V alloy specimens, leading to decreased hardness and monotonic properties, resulting in cyclic softening and no increase in fatigue strength. Bilinear behavior in the elastic strain-fatigue life curve was observed, with good concordance between predicted and experimental fatigue lives shown through adjustment using models.
