“…It must be highlighted that SS 630 had hardness within the range of the values assumed, considering the various heat treatments that can be used. However, the tensile test showed a particular behavior consistent with the strain-induced martensite formation (TRIP) effect observed by [ 1 , 23 , 24 ], resulting from a high retained austenite content. This effect led to higher ductility than conventionally heat-treated SS 630.…”

“…Note that 420 martensitic stainless steel has also been of significant interest in SLM, since its properties are suitable for specific applications, due to its high strength and corrosion resistance [ 18 ]. Consequently, many studies have been published concerning the microstructure, mechanical properties, and roughness of these stainless steels, produced by SLM ([ 19 , 20 , 21 ] −316L, [ 22 , 23 , 24 ]−630, [ 25 , 26 , 27 ]−420). SS 440C is also a martensitic stainless steel, but has high carbon content; it is used in applications where high hardness and corrosion resistance are necessary, such as bearings, knives and automotive parts [ 28 ].…”

Metal additive manufacturing (AM) has been evolving in response to industrial and social challenges. However, new materials are hindered in these technologies due to the complexity of direct additive manufacturing technologies, particularly selective laser melting (SLM). Stainless steel (SS) 316L, due to its very low carbon content, has been used as a standard powder in SLM, highlighting the role of alloying elements present in steels. However, reliable research on the chemical impact of carbon content in steel alloys has been rarely conducted, despite being the most prevalent element in steel. Considering the temperatures involved in the SLM process, the laser–powder interaction can lead to a significant carbon decrease, whatever the processing atmosphere. In the present study, four stainless steels with increasing carbon content—AISI 316L, 630 (17-4PH), 420 and 440C—were processed under the same SLM parameters. In addition to roughness and surface topography, the relationship with the microstructure (including grain size and orientation), defects and mechanical properties (hardness and tensile strength) were established, highlighting the role of carbon. It was shown that the production by SLM of stainless steels with similar packing densities and different carbon contents does not oblige the changing of processing parameters. Moreover, alterations in material response in stainless steels produced under the same volumetric energy density mainly result from microstructural evolution during the process.

The first part of the research project, which resulted in the Paper I, Paper II and Paper III, has been funded by the Swedish Energy Agency and Siemens Energy AB (formerly Siemens Industrial Turbomachinery AB) through the research programme Turbines for Future Energy Systems (Turbiner för framtidens energisystem), the support of which is gratefully acknowledged. The remaining part of the project, resulting in Paper IV and Paper V, has been funded by Linköping University and Siemens Energy AB. First and foremost, I would like to thank my main supervisor Associate Prof. Daniel Leidermark for your patience, encouragement and enthusiasm, and for always taking time for discussions, guidance, or anything I have on my mind. Special thanks goes also to Lic. Eng. Daniel Nilsson for all support you have provided me with regarding testing, application near questions, and for making it possible for at least some of our work to be used in "reality". I would also like to thank my research group; Prof. Kjell Simonsson, Dr. Jan-Erik Lundgren and Associate Prof. Robert Eriksson for your valuable input and support through the project.In addition, I would like to thank all Ph.D. colleagues at the Division of Solid Mechanics for, most importantly, making the Ph.D. studies a lot more fun, but also for all valuable discussions. A special thanks goes to my office mate Jordi for all your help, both at office and outside of work.Last, but not least, I would like to thank my girlfriend Ida for all your support. As we started our Ph.D. journeys almost at the same time, it has been invaluable to have someone to discuss things with at any time. However, most importantly, thank you for making my time outside work much more joyful.

This article presents the results of a study on the distribution of weld distortion in thin-walled components made of 17-4 PH steel, resulting from TIG (Tungsten Inert Gas) welding. Both manual and automatic welding processes were examined. Physical simulation of the automated welding process was conducted on a custom-built welding fixture. Analysis of weld distortion in thin-walled components made of 17-4 PH steel was based on the results of measurements of transverse shrinkage and displacement angle values. These measurements were taken on thin-walled parts before and after the welding process using a coordinate measuring machine (CMM). To determine the effect of manual and automated welding processes on the microstructure of the welded joint area, metallographic tests and hardness measurements were performed. The microstructure was analyzed using a scanning electron microscope (SEM). An analysis of the chemical composition of selected welded joint zones was also conducted. These tests were performed using an optical emission spectrometer (OES). According to the results, the use of automated welding and special fixtures for manufacturing thin-walled aircraft engine components made of 17-4 PH steel reduces the propensity of these components for distortion due to the effects of the thermal cycle of the welding process. This conclusion is supported by the results of the observation of the microstructure and analysis of the chemical composition of the various zones of the welded joint area.
