Summary: This study investigates the impact of laser shock peening surface treatment on corrosion-fatigue crack growth (CFCG) life enhancement of WAAM components made of ER70S-6 and ER100S-1 steel wires. The experimental results demonstrate the effectiveness of the examined surface treatment method for corrosion-fatigue life enhancement and crack growth retardation of WAAM built steel components, regardless of the material type and specimen orientation. Additionally, the measurement of residual stresses validates the influence of beneficial residual stresses on subsequent CFCG behavior of the material.

Summary: This study compares the mechanical properties of additively manufactured (AM) SS316L and conventionally manufactured (CM) SS316L and finds that AM SS316L has more dislocations and low angle grain boundaries, resulting in different strengthening mechanisms. Furthermore, the distribution of coincident site lattice boundaries is more diverse in AM samples. Additionally, the behavior of AM grain boundaries under tensile strain is significantly different from CM samples.

Summary: This study explores the surface morphology and geometric characteristics of single tracks in micro selective laser melting (MSLM), and optimizes process parameters through orthogonal experiments on density, surface roughness, microstructure, microhardness, and tensile strength. The research shows that heat treatment leads to grain refinement, uniform organization, and improved mechanical properties. The optimal process parameters are determined, resulting in high part density, low surface roughness, and increased tensile strength after SRAT + ST treatment. The study emphasizes the importance of laser power and scanning speed in ensuring the continuity of single tracks forming.

Summary: In this study, the surface microstructure of AISI 420 martensitic stainless steel was modified using laser shock peening (LSP) technique, and the deformation mechanisms were investigated through observing microstructural evolution. The results showed that laser shock wave caused severe deformation in the original sub micron carbide, leading to carbide fragmentation and promoting nanocrystallization of martensitic laths. Additionally, carbide decomposition occurred simultaneously with severe plastic deformation, and this, along with fine grain strengthening, precipitation strengthening, and dislocation strengthening induced by LSP, contributed to an increase in the strength and ductility of AISI 420 martensitic stainless steel.

Summary: Selective Laser Melting (SLM) process has the potential to create unique 3D components of AlSi10Mg with exceptional degrees of freedom for wide range of applications. However, the presence of porosity and other defects influenced by process parameters can be harmful to the fabricated components. This review provides a detailed description of the recent research on the SLM-AlSi10Mg, including the effect of process parameters on the mechanical properties of the alloy. The effect of heat treatments on the microstructure and overall mechanical properties of SLM fabricated AlSi10Mg alloy parts is also discussed. The findings reveal that the density of additively manufactured AlSi10Mg built part first increases with increase in energy density and then decreases above threshold value due to lack of fusion at low energy and at high energy key hole formation take place. Tensile strength of the built parts is affected by the process parameters, built direction, baseplate preheating temperature and built environment. The process parameters and built condition also affect the roughness and hardness of additively manufactured AlSi10Mg parts. Heat and surface treatment also help to improve the mechanical and surface properties by changing microstructure orientation. Furthermore, various surface finishing techniques based on energy sources such as mechanical, chemical and thermal can improve the surface roughness and fatigue life of SLM fabricated AlSi10Mg parts.
