“…After a tensile strength test, fractures were located in the heat-affected zone, where the presence of cementite was identified [19]. In order to accelerate the beginning of the bainite transformation, use of deformation in the welded joint was suggested by applying the rotary impacting trailed welding (RITW) method [22]. In this method, the welding and impacting occurs synchronously, which makes it possible to introduce compressive and shear stresses in the material at the same time during the welding process.…”

This article presents state-of-the-art welding methods and the weldability aspect of steels, particularly high-carbon nanobainitic (NB) steels, without carbide precipitates (CFB—carbide-free bainite). On the basis of research conducted to date, all welding methods with parameters and weld metals for NB CFB are presented. It was found that the process parameters significantly affected the mechanical properties of the welds, which were determined primarily by the properties of the low-temperature heat-affected zone. The microstructures of welded joints in the heat-affected and fusion zones are also described. The general requirements for welding processes, as well as problems and perspectives for further research, are presented.

“…Mechanical properties of plates made of steel NANOS-BA® subjected to heat treatment using parameters restricted within the ranges presented in Fig. 6 and of other nanobainitic steel grades [7,[22][23][24][25] approximately 2.1 GPa and the total elongation was 21.3%. In turn, in relation to steel containing 0.6% C in the variant characterised by the fraction of retained austenite volume amounting to 20%, the hardness amounted to 600 HV, R₀.₂ was approximately 1.5 GPa; R m amounted to approximately 2,0 GPa and the total elongation was 19%.…”

Steels belong to the most popular structural materials. Depending on their chemical compositions and applied heat or thermo-mechanical treatment, steels are characterised by various microstructures as well as diverse mechanical and functional properties. Recent years have seen the significant development related to the design of chemical compositions and manufacturing technologies used in the production of nanostructural steels. The article describes the methods used when manufacturing nanostructural steels and presents characteristics of selected i.e. high-strength nanobainitic steels in terms of their microstructure as well as mechanical and functional properties. The second part of the article is concerned with the present and prospective applications of nanobainitic steel products as well as summarises information found in related reference publications regarding the above-named steels.

“…The analysis of reference publications concerning the welding of nanobainitic steels led to the conclusion that the issue is not very well known [6][7][8][9]. To identify the applicability of bainitic steels it was necessary to perform welding tests concerning the above-named steels and determine the effect of a welding thermal cycle on changes in the microstructure and hardness in the welded joint.…”

“…Additional impact treatment accompanying the welding process made it possible to control the microstructure of the welded joint. As a result of impact and heat treatment, Fang et al [9] increased the amount of bainite (from 40% to 80%) and refined bainite laths in the weld of a TIG-welded joint.…”

Intense research on the metallurgy of iron alloys have recently resulted in the development of technologies enabling the making of high-carbon nanobainitic steels. Because of their chemical composition, the above-named steels belong to hard-to-weld materials. To identify the possibility of welding such steels using arc-based methods and welding in the solid state it was necessary to make test joints and perform related metallographic tests. The test results revealed that it is possible to obtain both fusion and pressure welded joints if the process was performed in the softened state, i.e. before the final heat treatment. Afterwards, joints should be subjected to a heat treatment ensuring the obtainment of a previously assumed microstructure and required hardness distribution in the weld and HAZ.
