eaf plants normally consume coal and coke as reactants, alloying elements, or fuel. the price of these materials varies from € 0.20-0.35/kg. this is while nearly 10 million pieces of tires are annually discarded in iran. the present study shows that scrap tires can be used as a substitute for coal and coke in eaf plants. thirteen grades of steel including low, medium, and high carbon steels as ...

The biodegradable inhibitors, which could effectively reduce the rate of corrosion of carbon steel, were investigated by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The mixed-type inhibitors extracted from Eriobotrya japonica Thunb. leaf exhibited excellent inhibition performance, and the inhibition efficiency for carbon steel reached 90.0% at 298 K in hydroch...

Abstract Constrained groove pressing (CGP) is one of the severe plastic deformation techniques for sheet metals to impose large strain and produce ultrafine-grained (UFG) structures without any change in dimensions. Cross route-constrained (Cross-CGP), an advanced version conventional CGP process, involves two cycles with equivalent 2.32 per cycle where square sample rotated by 90° after perfor...

Three types of self-piercing riveting (SPR) joints, i.e., steel/aluminum, carbon fiber reinforced polymer (CFRP)/ aluminum, and aluminum/aluminum, were constructed using three different top sheet materials with the same aluminum alloy as bottom sheet. The effects material on joint quality mechanical behavior evaluated. materials’ characteristics dominate rivet piercing process consequent interl...

this work is an attempt towards employing ductile damage criterion and finite elementsimulations for prediction of fracture initiation and evolution in deep drawing of copper/stainlesssteel clad sheets. the material mechanical properties and ductile damage parameters weredetermined through standard and notched tensile tests. the effect of some important processparameters on damage evolution wer...

This paper deals with the eff ects of technological parameters used in the V-die bending process, on the obtained product properties and dimensions. By variation of the tool geometry, several cases of steel sheet bending process are observed through the FEM simul...

Carbonitriding of four types of steels, namely, low carbon steel (LCS), medium carbon steel (MCS), low alloy steel (LAS) and high alloy steel (HAS) was achieved using cyanide salt bath heat treatment process. The steels, after preheating, were heated in a diesel fired salt bath heat treatment furnace and then quickly quenched in different media including air, oil and brine. The heat treatment p...

The study reports the mechanical property and microstructure of cold rolled low carbon steel and its work-hardening behavior in the deformation process. The tensile test in room temperature of low carbon steel was implemented for the different cold rolling deformation, the stress-strain curve was draught according to the relationship between strength and deformation and fitted for the polynomia...
