In this paper, the Shape Memory Steel (SMS), a new kind of ferrous SMA Mn family and complemented with Cr additions, is introduced as very interesting smart material, able to be used in fitting reshaping applications, potential being structural reinforcement applications [...]

An elaborative study was carried out on the growth mechanism and properties of the passive film for a new kind of alloyed corrosion-resistant steel (CR steel). The passive film naturally formed in simulated concrete pore solutions (pH = 13.3). The corrosion resistance was evaluated by various methods including open circuit potential (OCP), linear polarization resistance (LPR) measurements, and ...

The study results of the structure and properties layer deposited with flux-cored wires Fe-C-Si-Mn-Cr-Mo-Ni system additionally alloyed titanium are presented. Surfacing investigated was carried out on a substrate made 09G2S steel using silicomanganese slag flux.

Increasing interest in graphene research in basic sciences and applications emphasizes the need for an economical means of synthesizing it. We report a method for the synthesis of graphene on commercially available stainless steel foils using direct thermal chemical vapor deposition. Our method of synthesis and the use of relatively cheap precursors such as ethanol (CH(3)CH(2)OH) as a source of...

The growth kinetics of ferrite during intercritical annealing steel has been investigated using in situ high energy X-ray diffraction with a specially designed furnace allowing highly quantitative measurements phase volume fractions. Kinetics have obtained at 730?C, 750?C and 775?C different ternary Fe-C-X (where X : Mn, Ni, Mo Cr) alloys quaternary Fe-C-1Mn-1Cr (wt.%) alloy. results were compa...

The chemical modifications introduced in the passive layer of AISI 304 stainless steel after Si, Ce, and Mo ion implantation were investigated and compared with non-implanted steel by soft X-ray absorption spectroscopy. The influence of ion implantation on the passive properties was evaluated by measuring soft X-ray absorption spectra at the Cr, Fe, Ni, Mn and Si 2p in addition to oxygen 1s thr...

The grain boundary oxidation mechanism in hot rolled steel samples during cooling from 500 °C – 800 °C down to room temperature was mathematically modeled. Given a fixed temperature ramp, the migration of the atomic species (iron, oxygen and the alloying elements) has been calculated with the parabolic rate equation for diffusion. After each small time step, the data was transferred into the da...
