The possibility of producing bainite at low temperatures by suppressing transformation using substitutional solutes has been investigated, as an alternative to using large carbon concentrations to achieve the same purpose. It is found that although transformation temperatures can indeed be suppressed in this way, the difference between the bainite and martensite start temperatures diminishes. T...

this paper focuses on the optimization of initiating dimensions of groove bearing in association with de- sired design of vehicle’s front structure which is made up of low carbon steels in the case of frontal collision. axial bearing analysis is done numerically using nonlinear finite element code ls-dyna. in this analysis, changes of two main parameters including measure of energy absorption o...

The influence of Mn addition on fatigue properties ferritic steel containing solute carbon was examined using rotating bending tests water-quenched Fe–0.016C–1.9Mn ferrite–pearlite 0.0035 mass% in comparison with Fe–C steels 0.0063–0.017 carbon. were carried out at ambient temperature around 300 K and a frequency 50 Hz stress ratio −1. Fe–C–Mn exhibited comparable hardness limit to the Fe–0.017...

This Study about output parameter of Non Traditional machining, i.e., Which are not used conventionally like Electrical Discharge Machining (EDM) is a machining method primarily used for hard metals or those that would be very difficult to machine with traditional techniques, here it is used for cryogenically treated work piece. In simple terms, EDM is a manufacturing process whereby a desired ...

High-strength-low-alloy reinforcement bar steels prepared by vanadium microalloying methods have the potential to dramatically reduce embodied energy and carbon footprint of buildings.

The novel Cr-containing low alloy steels have exhibited good corrosion resistance in CO₂ environment, mainly owing to the formation of Cr-enriched corrosion film. In order to evaluate whether it is applicable to the CO₂ and H₂S coexistence conditions, the corrosion behavior of low-chromium steels in CO₂-H₂S environment with high pressure and high temperature was investigated using weight loss m...

It is conventionally assumed in the mass production of steels that the processing time must be reasonable and that the material must have uniform properties. The consequence is that short heat-treatments cannot be tolerated since the scale of engineered products may be so large that uniform temperatures cannot be achieved. Similarly, thermal treatments requiring several days or weeks are not co...

in this research formability behavior and texture of st14 low carbon steels produced by foolad mobarakeh plant for deep drawing application had been studied. plate textures were characterized by x-ray diffraction technique. to evaluate formability behavior one dimensional tensile test was carried out and related parameters were recognized. moreover eriksson experiment and spherical pattern prin...

The toughness of martensitic steels is strongly related to their fine and complex morphologies. To control the steels, effect carbon content on morphology lath martensite must be studied. However, these morphological changes are difficult clarify using conventional two-dimensional observations because morphologies tangled. Previously, we analysed reported three-dimensional microstructures ultra...
