the effect of chloride ions concentration on the electrochemical behavior of aisi 410 stainless steel in thesimulated concrete pore (0.1 m naoh + 0.1 m koh) solution was investigated by various electrochemicalmethods such as potentiodynamic polarization, mott–schottky analysis and electrochemical impedancespectroscopy (eis). potentiodynamic polarization curves revealed that increasing chloride ...

Release of nickel from nickel or nickel-plated metals, is often responsible for allergic contact dermatitis. However, the effect of nickel-bearing stainless steels is not weil known. ln this paper AISI 304, 316 and 430 type stainless steels, as weil as nickel and nickel-plated materials, are investigated. Three tests were carried out: electrochemical tests and leaching experiments in sodium chl...

The application of conductive coatings on ferritic stainless steel can decrease electrical conductivity. Theaim of this research was to investigate the electrical conductivity of cobalt coated AISI 430 ferritic stainlesssteel by pack cementation technique. Coated coupons were analyzed using scanning electron microscopy(SEM). Electrical conductivity of the coated substrates was measured as a fun...

A high quality joint between tool steel and stainless steel alloys is hard to achieve with the conventional welding process. In this study, a new process of joining semi-solid AISI D2 tool steel and AISI 304 stainless steel using a partial remelting method is proposed. Metallographic analysis and Vickers hardness tests were performed. The results obtained from investigating the basic geometries...

The effect of chloride ions concentration on the electrochemical behavior of AISI 410 stainless steel in the simulated concrete pore (0.1 M NaOH + 0.1 M KOH) solution was investigated by various electrochemical methods such as Potentiodynamic polarization, Mott–Schottky analysis and electrochemical impedance spectroscopy (EIS). Potentiodynamic polarization curves revealed that increasing chlori...

The use of the ultrafast heating (UFH) heat treatment process attracted great attention in last few years, following requirements CO2 emissions reduction. The
 effect an AISI 441 ferritic stainless steels is reported this paper. Results show that a minimum temperature 975 °C required order to achieve fully recrystallized microstructure. study highlights ultrarapid annealing on grain size e...

Intergranular stress corrosion cracking has occurred in BWR environments in non-sensitised, cold-worked austenitic stainless steel materials. The affecting parameters are so far not fully known, but deformation mechanisms may be decisive. The effect of cold deformation and nitrogen content on the deformation behaviour of austenitic stainless steels was investigated. The materials were austeniti...

Complex two-component peak of anelastic mechanical losses was observed in multicomponent substitutional austenitic alloys after prior plastic deformation. In AISI 316L, AISI 316LN, AISI 310 and AISI 304 austenitic stainless steels, this peak is situated in the wide range of temperature from 200 to 400K. Characteristics of the observed peak for different thermo-mechanical treatments were studied...

Abstract In recent years, due to the installation of selective catalytic reduction (Selective Catalytic Reduction, hereinafter referred as SCR) devices, high temperature oxidation failure has occurred frequently in automobile exhaust systems. To explore its mechanism, this paper takes 439 ferritic stainless steel which is often used pipes an example and uses XRD, SEM, EDS experimental methods s...
