At the same time, AISI 316L is an economical and easily processable material. Indeed, the low carbon content prevents sensitisation of heated areas around the molten tracks in l -PBF process and it preserves dislocations mobility in the iron crystal lattice, thus reducing material hardness and brittleness [8].
Milton et al. studied the microstructure of DED AISI 316L and revealed that Cr and Ni equivalent contents lie in the range of 5–10% δ-ferrite []. Zietala et al. also investigated DED of AISI 316L and found that intercellular δ-ferrite formed at sub-grain boundaries as a].
Optimization of welding parameters by using the Taguchi methodology in a narrow joint of API 5L X-52/AISI 316L-Si bimetallic plates welded by the gas metal arc welding process was performed. The hot pass was deposited with an ER-Ni-1 electrode varying the thickness and subsequently filled with an ER-70S-6 filler wire. The results of …
Consequently, in the present work the influence of a stress-relief heat treatment on the cyclic properties of SLM specimens made of austenitic stainless steel AISI 316L was investigated. Therefore, heat treated specimens were compared to former results on non-heat-treated SLM specimens (published in [5]), manufactured with identical …
Additive manufacturing (AM) has emerged as an outstanding technique for obtaining complex geometries and custom parts, without the material loss of conventional subtractive manufacturing processes. In this work, AISI 316L stainless steel specimens were fabricated by laser powder bed fusion (L-PBF), and its microstructure was characterized …

The AISI 316L test specimens were manufactured by a laser cladding system (PRECO, SL 8600), as shown in Fig. 2. A diode laser source (Laserline, LDF6000-60VGP) provided with a continuous wave (CW) near-infrared (NIR, λ laser = 980–1060 nm) laser beam, with spot size of 2.0 mm and a maximum average power of 6.0 kW, was used.
Nanostructured materials exhibit superior properties with respect to their bulk counterpart. Recently, a new processing method for surface nanostructuring of metallic materials called surface mechanical impact treatment (SMIT) was developed. In this study, the surface microstructural features due to the refinement process of AISI 316L stainless …
In the present study, compositionally-graded structures of AISI 316L and CoCrMo alloy are manufactured by powder-based laser-beam directed energy deposition (DED-LB). Through a process-integrated adjustment of powder flow, in situ alloying of the two materials becomes feasible. Thus, a sharp and a smooth transition with a mixture of …
This work aims at the improvement of surface quality and wear resistance of AISI 316L stainless steel, used in different industrial sectors including orthopedic applications. Ball-burnishing treatment, considered as a very efficient mechanical finish process, was applied with respect to the response surface method. Surface roughness …
More specifically, the Fireworks algorith is employed to determine the appropriate material parameters for AISI 316L steel. The results indicate a sufficient performance of the optimization approach, which can be further developed and applied for other ty es materials as well. © 2018 The Authors.
Intergranular corrosion is one of the most important processes affecting the behaviour of austenitic stainless steels. Factors such as steel chemical composition, the degree of prior deformation and the exposure temperature affect the degree of sensitisation. AISI 316L (0% CW) steel was annealed at 650 °C for 5, 10, 30, 100, 300 and 1000 h to …
Directed energy deposition (DED), one of the additive manufacturing (AM) technologies, was used to realize AISI 316L specimens. The role of substrate preheating on the microstructure, hardness, surface roughness, and mechanical properties of AISI 316L samples was studied using two groups of deposited samples on a cold substrate and a …
AISI H13 hot-work tool steel and AISI 316L low-carbon stainless steel powders were employed as feedstock materials to produce the FGM deposit over an AISI 1045 mild steel substrate. The powder particle size of the feedstock employed was 53–150 µm for the AISI H13 powder and 45–125 µm for the AISI 316L powder.
The subject of this work was the study of processes occurring during sintering of water atomized AISI 316L austenitic stainless steel powder modified by the addition of graphite nanoparticles.
