Abstract:
The susceptibility to the hydrogen embrittlement of commercial heat of TRIP 780 steel of the type C-Mn-Si was studied on previously hydrogenated samples by a slow strain rate tensile tests (SSRT) in the initial state and in the state after 5% deformation in the longitudinal and transverse directions relative to the rolling direction. Samples were hydrogenated in 0.1N sulfuric acid solution with the addition of KSCN. [..]

Abstract:
The paper wants to be a review of the own researches realized in the nonconventional treatments domain, corresponding to the magnetic field treatments applied to a steel of construction for industrial parts, for gears and some parts of industrial machines. The magnetic field applied under certain conditions during the cooling process of the sample in the case of the improvement treatments, modifies the properties of steel, the hardness, the corrosion resistance and the wear resistance increase.The studies on tribomodels during the dry friction processes determine the wear intensity for a certain type of tribomodel and for a certain type of material.

Abstract:
The influence of heat treatment on the microstructure, mechanical and sliding wear properties of Hastelloy C-276 HVOF sprayed coatings was evaluated. The applied furnace heat treatment modified the coatings microstructure, leading to precipitation hardening and oxidation of inter-splat boundaries, but had a negative effect on the sliding wear resistance.

Abstract:
In this article, the reactions and optimal parameters were investigated for molybdenum layers produced on aluminum substrate using single beam ytterbium fiber laser. To produce these layers the molybdenum powder (25–45 µm in size) was placed on the aluminum sheet substrate and successfully treated – along the entire length with 16 different irradiation modes.

Abstract:
The results of the hydrogen concentration measurements in selected products, made of steel grade 41Cr4, are presented in the following paper. The reason for this project was the failure of the tower structure and the suspicion of brittle fracture caused by hydrogen in one of the hot-dip galvanized products made of steel grade 41Cr4, found in the wreckage of the tower.
