The current work demonstrates the microstructural evolution and mechanical property evaluation of a newly designed steel composition after hot rolling in laboratory-scale mill, followed by continuous cooling. thus developed has typically about 80% carbide-free bainite; 20% retained austenite can deliver ∼1400 MPa ultimate tensile strength along with more than total elongation. presence ultra-fine bainite plates (∼100–130 nm thick) high dislocation density was thought to be responsible for...
Abstract A carbide-free bainitic microstructure is suitable for achieving a combination of ultra high strength and ductility. In this work, steel containing nominally 0.34C-2Mn-1.5Si-1Cr (wt.%) was produced via industrial hot rolling laboratory heat treatments. The austenitization (900°C, 30 min.) austempering (300-400°C, 3 h) treatments were done in salt bath furnaces. designed to approximately simulate the coiling step, following run-out-table cooling, when transformation would take place...
A hot rolled steel with unique combination of high strength and excellent ductility coupled hole expansion ratio has been developed for automotive applications using a new metallurgical approach. The chemistry processing parameters were designed in such way that austenite–ferrite phase transformation takes place at lower temperature interphase precipitation very fine carbides. ferritic microstructure was produced an average grain size 3·4 μm resulting into attractive mechanical properties....
The effect of short duration tempering on the microstructure and mechanical properties a continuously annealed dual phase steel was investigated using techniques like electron microscopy, dilatometry thermodynamic calculations. It found that complex interplay phenomena martensite, quench aging ferrite recovery overall structure responsible for change in recorded.
The effects of ferrite–pearlite and ferrite–martensite starting microstructures on ferrite grain sizes carbide particle after cold rolling prolonged annealing treatment have been investigated. Ferrite–martensite showed finer improved tensile properties cycle compared to microstructures. A ‘fibrous’ martensite morphology developed by intermediate quenching is more beneficial in that respect the ‘blocky’ obtained from step treatment.
The warm rolling and subsequent annealing textures of an extra low carbon (ELC) two interstitial free (IF) steels have been investigated using both single pass multipass in the ferritic temperature range. A total amount 80% deformation by was given each case. It observed that texture development ELC IF during displays striking differences. In general, acquire only a weak after finish upper range, for rolling. Single lower however, produces very sharp γ fiber this alloy, as exception....
The present study concerns the mechanical properties of low carbon (0·05 wt-) high Mn bainitic steel. continuous cooling transformation diagram exhibited without any prior diffusive austenite even for a rate as 0·5°C/s. steels have shown elongation behaviour with attractive combination strength (>1200 MPa) and (>14). microstructure obtained after annealing treatment has yielded excellent strength, uniform elongation, yield ratio static toughness value.
