In this paper, the semiconducting behavior of carbon steel in acid, base and salt solutions was studied by utilizing potential-capacitance and Mott-Schottky analysis. It was pointed out that the capacitance variation of space charge layer of carbon steel in different solution was different. The carbon steel showed p-type semiconducting behavior in 5% sulfuric acid and 5% sodium sulfate solution...
In this work, three low-carbon bainitic steels, with different Mo contents, were designed to investigate the effects of Mo addition on microstructure and mechanical properties. Two-step cooling, i.e., initial accelerated cooling and subsequent slow cooling, was used to obtain the desired bainite microstructure. The results show that the product of strength and elongation first increases and the...
behaviors of stress corrosion cracking (scc)in martensitic stainless steel(aisi 420) and low carbon austenitic stainless steel (aisi 316l) have been compared under different conditions of temperature, environment (mgcl2), and strain rate. the results show that decreasing strain rate has detrimental effect on mechanical properties of both steels, including their strength and ductility. fractogra...
Citation Suresh Kumar K. Numerical modeling of an autogenous butt joint welding of low carbon ferritic steel sheets using a pulsed Nd: YAG laser beam.
Nigeria is blessed with abundant iron ore deposits of nearly 3 billion tonnes and other basic minerals for steel production including coal and limestone. Yet the Nigerian steel sector has collapsed principally due to shortage of raw materials particularly iron ore for the integrated steel plants and billets for the rolling mills. The privatization of the steel sector that was done in 2004-2005 ...
We describe here for the first time the low temperature superplasticity of nanostructured low carbon steel (microalloyed with V, N, Mn, Al, Si, and Ni). Low carbon nanograined/ultrafine-grained (NG/UFG) bulk steel was processed using a combination of cold-rolling and annealing of martensite. The complex microstructure of NG/UFG ferrite and 50-80 nm cementite exhibited high thermal stability at ...
in this paper, an ultra low carbon high strength low alloy grade steel was subjected to a two-step forging processand this was followed by different post cooling methods. the highest strength was obtained at a faster coolingrate due to the highly dislocated acicular ferrite structure with the fine precipitation of microalloying carbides andcarbonitrides. at a slow cooling rate, the strength fel...
Recrystallization Behavior of Deep Drawing Low Carbon Steel Sheets Produced by Mobarakeh Steel Plant
In the present work the recrystallization behavior of deep drawing grade Al-killed low carbon steel sheets produced by Mobarakeh Steel Plant (MSP) has been studied. Salt bath isothermal annealing has b...
