Abstract: Twinning Induced Plasticity steel, or TWIP steel, has had increased interest in recent years from various industry sectors. This is due to it being light weight, strong, and ductile; which are all properties that are useful in the automotive and aerospace industries. [..] Read more

Abstract: Simulation of iron alloy corrosion is widespread used to predict corrosion resistance. The simulation using corrosion chambers or climatic chambers provides reasonable information on corrosion resistance, the corrosion rate however must be compared to real exposition as the corrosion in simulated environment is accelerated compared to real situation.

Abstract: Ductile iron with 1.56% Ni was subjected to various cycles of the austempering treatment. For all variants, the austenitization temperature was 920oC and the time of holding was 2 hours. [..] Read more

Abstract: The presented paper is devoted to the comparison of hydrogen diffusion characteristics in three different kinds of TRIP steels (with higher phosphorus content, higher aluminum content and higher silicon content). The steels were tested in as-received state after standard heat treatment including two step annealing – an intercritical annealing and an annealing in the range of bainitic transformation and in states after 5 % and 10 % tensile deformation.

Abstract: This paper deals with a comparison between the standard spring steel grade 0.54C-1.45Si-0.7Mn-0.7Cr and a grade micro-alloyed spring steel with 0.12 % V in terms of microstructure, grain refinement, strength and ductile properties. The micro-alloyed steel is supposed to provide a better performance as it had been proven for hot-rolled and heat treated wire. [..] Read more

Abstract: Austenitic Stainless Steel is known as responsible for the largest manufacturing share of stainless steel. Different processes, as well as the addition of alloying elements affects the microstructure, which provides specific properties to each steel grade. [..] Read more

Abstract: The crucial role in the case of any FEM simulation play input data. There is significantly increasing demand on material data measurement for FEM simulation and on their accuracy. [..] Read more

Abstract: This paper attempts to study safety and exploitation conditions of long weld steel structures. To study the effects of the long structure flexibility and resistance, the structure been welded by steel covered electrodes with varied amount of Mo. [..] Read more

Abstract: The article presents a review of the most new structure materials that currently are being applied to production of different vehicle elements. The main purpose of the article is to draw attention to the materials applied to fabricate this kind of elements. [..] Read more

Abstract: Steel construction needs to present high plastic properties especially during dynamic load. It is necessary for impact conditions. [..] Read more

Abstract: In archaeology, the Iron Age is the period when the iron usage and the technological processes of its obtaining were the most important for the society. The Iron Age is the last period from the system of the three ages of classifying the prehistoric societies, preceded by the Bronze Age. [..] Read more

Abstract: This research paper deals with an effect of injection mold core/cavity surface and their additional treatment on selected optical properties and surface quality of these tool parts. Used mold cavities were made from tool steels 1.2343 (chromium-molybdenum-vanadium-silicon steel with good hardenability) and 1.2083 (martensitic steel with high chromium content), their surface was polished to the roughness of Ra = 0.08 microns (manufacturer guaranteed mirror finish). [..] Read more

Abstract: Blast-cleaning is one of the often-used technologies of surface pre-treatment. Its main use is in the area of anticorrosive protection of materials, as the last technological operation prior to the creation of protective coating. [..] Read more

Abstract: Composite (Ni) + Ni3Si coatings on C45 steel-substrate could be easily developed via three-step technology: electrodeposition of nickel interlayer, sediment co-deposition of Ni+Si and subsequent vacuum annealing at 980 C for 5 h. The results of hardness measurements showed that as-plated Ni+Si coating was 1.7 times harder than the electrodeposited Ni coating, but the hardest was (Ni) + Ni3Si coating (820 HV) due to the presence of the super hard Ni3Si phase. [..] Read more

Abstract: Early steel bars corrosion in reinforced concrete elements are difficult to detect because of the lack of visible changes on the concrete surface. To assess reinforcement corrosion risk level without structure damage some non-destructive diagnostic methods are applied. [..] Read more

Abstract: Electrochemical chloride extraction from a reinforced concrete structure may be accompanied by an electrochemical injection of healing agents if such agents are positively charged and are able to migrate towards the activated reinforcement. Nanoparticles carrying a positive or cathionic corrosion inhibitors might be the proper choice. [..] Read more

Abstract: One of the most important two–phase alloys α+β is Ti–6Al–4V, which is frequently used in medicine. This alloy is characterized by innovative combination of strength, good corrosion resistance in the environment of chlorides, the highest biotolerance and the lowest Young's modulus. [..] Read more

Abstract: The work presents the effects of the change of the laser cladding parameters on microstructure, chemical composition and mechanical properties of Inconel 686 overlays (coatings). To obtain the best quality of these coatings the various parameters of laser cladding such as the power density of the laser beam, the laser beam velocity and overlapping ratio of the weld tracks were applied. [..] Read more

Abstract: An original method was recently developed for an assessment of residual stresses in case-hardened steels based on S-N curves of hardened and virgin samples along with the measurement of location of fish-eye crack centres. This method is applicable only when the surface of virgin specimens is sufficiently smooth to avoid the initiation of fatigue cracks from large surface defects. [..] Read more

Abstract: In this study, special ceramic coatings were prepared on low carbon steel (1.0060 – EN 10027-2) via the plasma spraying technique using a WSP®-H plasma generator with output of up to 40 kg/h of aluminum oxide. Corundum coatings were deposited directly on the surface of steel plungers equipped with an anti-corrosion interlayer of zinc phosphate. [..] Read more
