Basic properties of the suggested phenomenological model of tribocorrosion wear are considered. Using a friction pair austenitic stainless steel-ceramic in acid electrolytes as an example, a good agreement between predicted data and experimental evidence was obtained.

A significant problem in the concurrent application of transcranial magnetic stimulation (TMS) and functional magnetic resonance imaging (fMRI) is the image artefact caused by the effect of the TMS-coil on the homogeneity of the static magnetic field (B0). The resulting field inhomogeneity can lead to spatial distortions and local signal loss in echo-planar (EP) images. Here we demonstrate that...

Plates of austenitic stainless steel are often used in orthopedic surgery for fixing ends of the broken bones and for repairing fractures. The paper analyzes a premature breakage of six plates for fixing broken bones with different patients during their recovery. Each plate's breakage can induce serious aftermaths such as a new surgery, unexpected undesired complications and a prolonged healing...

austenitic stainless steels are extensively used in various applications requiring good corrosion resistance and formability. in the current study, the formation of nano/ ultrafine grained austenitic microstructure in a microalloyed aisi 304l stainless steel was investigated by the advanced thermomechanical process of reversion of strain-induced martensite. for this purpose, samples were subjec...

Hot–press forming steels are formed in a fully austenitic state followed by die– quenching in order to generate martensite and achieve a strong steel. The ductility however, tends to be limited. We explore in this work a novel steel design in which the forming operation is in the two–phase austenite and ferrite field, so that the quenching results in a dual–phase ferrite and martensite microstr...

The resistance and susceptibility of austenitic stainless steel, Type 304, exposed to strong tetraoxosulphate (VI) acids (2 and 5 M concentrations) contaminated with sodium chloride at ambient temperatures was investigated by gravimetric and metallographic/scanning electron microscopy surface characterization methods. Scanning electron microscope (SEM) was used to examine and characterize the t...

Résumé : In this paper, two methods were applied to determine the different elastics constants of the face centered cubic austenitic stainless steel Fe0.62Cr0.185Ni0.185. Firstly, the quantum mechanical simulation was applied based on the first principles calculations within the generalized gradient approximation (GGA) by using the efficient strain-stress method. Secondly an artificial neural n...

In this paper, a new technology for a novel material inherent load sensor for sheet metal components of metastable austenitic steel is presented. The new technology is based on load induced martensite formation and is investigated in the Collaborative Research Centre (CRC) 653. The sensors are small areas in the sheet metal material, which have been plastically deformed by means of stamping. Du...

Surface roughness is a result of the cutting parameters such as: cutting speed, feed per tooth and the axial depth of cut, also the tool’s geometry, tool’s wear vibrations, etc. Moreover, the surface finish influences mechanical properties such as fatigue behaviour, wear, corrosion, lubrication and electrical conductivity and the combination of cutting parameters influence the power consumption...

A patient who recently came under my care had been struck in the right eye by a foreign body whilst hammering a piece of steel with hammer and cold chisel. A diagnosis of intra-ocular foreign body was made, there being a small entrance wound in the centre of the cornea and an opaque lens. This diagnosis was confirmed by x ray. The foreign body, measuring about 3j x 1 x 1 mm. was located in the ...
