Cold-rolling and inter-critical annealing of low-carbon steel: Effect of initial microstructure and heating-rate
TL;DR: In this paper, the effects of starting microstructure and heating rate on the intercritical annealing treatment have been investigated by 80% coldrolling of different initial microstructures namely ferritepearlite and ferrite-martensite with blocky and fibrous martensitic morphologies.
Journal ArticleDOI
Effect of composition and thermo-mechanical processing schedule on the microstructure, precipitation and strengthening of Nb-microalloyed steel
TL;DR: In this article, the influence of composition and thermo-mechanical processing schedule on the kinetics of austenite recrystallization, strain induced precipitation and final microstructural evolution in Nb-microalloyed steels was studied.
Journal ArticleDOI

TL;DR: In this paper, cold-rolled samples of different starting microstructures, namely ferrite pearlite (F+P) and ferrite-martensite structures, with blocky martensite (Mb) and fibrous Martensite morphologies were reheated at two different heating rates (1 and 300 K/s) to sub-critical and inter-critical annealing temperatures [773-K to 1173-K (500-°C to 900 °C) and immediately quenched.
Journal ArticleDOI
Effect of microalloying elements on austenite grain growth in Nb–Ti and Nb–V steels
Anish Karmakar,Saurabh Kundu,Somnath C. Roy,Suman Neogy,Dinesh Srivastava,Debalay Chakrabarti +5 more
TL;DR: In this paper, the development of austenite grain structures have been compared in two different microalloyed steels (Nb-Ti and Nb-V steels) and one Al killed C-Mn steel, after soaking at 950-1250°C for 1 h.
Journal ArticleDOI
Development of Bimodal Ferrite-Grain Structures in Low-Carbon Steel Using Rapid Intercritical Annealing
TL;DR: In this article, the effect of heating rate on microstructural morphologies during intercritical annealing has been studied, and the results showed that fine-scale dual-phase structures showed superior combination of tensile strength and ductility compared to the ultrafine-grained steels.
