High-strength lightweight constructions are a crucial part of transportation systems and steel constructions optimised for low energy consumption. In this investigation, the aim is to understand the influence of different alloying elements on the mechanical properties of all-weld metal samples of high-strength filler metals. Metal-cored wires with adjusted chemistry were produced and the measured yield strength is compared with calculated values which were obtained by thermodynamic and kinetic simulations. By increasing the content of the matrix alloying elements, no increase in strength could be achieved, but compared to that, higher strength was obtained by the addition of Ti, Nb and Al in combination. Furthermore, the influence of different Ti, Al and N contents is presented and discussed.

“…Moreover, the dispersed M-A islands that have less carbon and alloy elements are precipitated and distributed in the fine bainite ferrite. Due to the discomposing of particle M-A into the ferrite and carbide during tempering at 660 °C, the M-A constituent can be changed into ferrite and carbide clusters [ 36 ]. After intercritical normalizing at 740 °C, the welding joint is tempered at 660 °C for 2 h. The weld and heat-affected zone microstructure are shown in Figure 5 .…”

Weld and base metals require hot or cold working during the steel equipment manufacturing process. As a result, the components should be subjected to a normalizing heat treatment in order to recover their mechanical properties. In this study, the submerged-arc welding of the high strength low alloy (HSLA) thick steel plate(13MnNiMoR) is adapted for the vessel head under the normalizing and tempering heat treatment. The findings showed that the material toughness decreases after heating to simulate a vessel head forming process. The stamping process is carried out under the conditions of 980 °C for one hour, normalizing at 920 °C for 1 h and tempering between 600–660 °C for 2 h, respectively. The martensite-austenite (M-A) constituent is distributed in granular bainite and the boundary of austenite in island constituent. Therefore, it was deemed to be the most detrimental to Charpy-V impact toughness. Between normalizing and tempering, intercritical normalizing at 740 °C was added. As a result of the ferrite with fine particles M-A constituent, the toughness increases significantly.

“…The Berkovich indenter generates dislocations organized in a quite complex way during a nanoindentation test, even for very low deformations [33], making difficult the formulation for the stress field generated, even during an elastic deformation, as well as its modelling. Most of the dislocations stay generally confined around the residual imprint in a dense structure [34,35] with many dislocation interactions [36]. The ratio of hardness/elastic (H/E) modulus is of significant interest in tribology.…”

-This study is focused on the investigation of the morphology and the characteristics of carbon films, obtained by thermal chemical vapor deposition (T-CVD) on different substrates, during carbon nanotubes (CNTs) manufacturing. These films were examined, by means of optical and electronic microscopy, X-ray photoelectron spectroscopy and Raman spectroscopy. Additional measurements were conducted related with the estimation of their nanomechanical properties. The topography is studied, in combination with the assessment of their mechanical behavior at nanoscale. Through nanoindentation, hardness and elastic modulus together with wear resistance index (H/E) were evaluated. According to this study, it may be remarked that the obtained film is classified as an amorphous carbon film.
