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 ...

Strength and ductility are mutually exclusive if they are manifested as consequence of the coupling between strengthening and toughening mechanisms. One notable example is dislocation strengthening in metals, which invariably leads to reduced ductility. However, this trend is averted in metastable austenitic steels. A one-step thermal mechanical treatment (TMT), i.e. hot rolling, can effectivel...

The measurement of absorptance is important for the analysis and modelling of laser-material interactions. Unfortunately, most of the absorptance data presently available considers only polished pure metals rather than the commercially available (unpolished, oxidised) alloys which are actually being processed in manufacturing. This paper presents the results of absorptance measurements carried ...

This article introduces the microstructural and mechanical properties of low medium-carbon advanced martensitic steels (AMSs) subjected to heat-treatment, hot- warm- working, and/or case-hardening processes. The AMSs developed for sheet wire rod products have a tensile strength higher than 1.5 GPa, good cold-formability, superior toughness fatigue strength, delayed fracture due mixture martensi...

Abstract. High-Mn steels have great plasticity when subjected to deformation due TWIP or TRIP effects. This work evaluated the microstructural evolution, formation of -Martensite phase taking into account hot rolling 80-60% and solution annealing. Afterwards, microstructures were analyzed by SEM. Volume fraction Austenite phases measured EBSD technique. The steel obtained low energy levels sta...

Mathematical expression describing plastic behavior of steels allows the execution of parametric studies for many purposes. Various formulas have been developed to characterize stress strain curves of steels. However, most of those formulas failed to describe accurately the strain hardening behavior of steels in the full range which shows various distinct stages. For this purpose, a new formula...

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...
