Ultra-Fine Grained Dual-Phase Steels
This paper provides an overview on obtaining low-carbon ultra-fine grained dual-phase steels through rapid intercritical annealing of cold-rolled sheet as improved materials for automotive applications. A laboratory processing route was designed that involves cold-rolling of a tempered martensite structure followed by a second tempering step to produce a fine grained aggregate of ferrite and ca...

متن کاملUltra-fine Grained Bulk Steel Produced by Accumulative Roll-bonding (arb) Process
Much attention has been directed recently to ultra-grain refining of metallic materials, where the grain size is reduced to less than 1 mm. It is expected that submicrometer grained structure would result in high strength and toughness at ambient temperature [1] as well as high strain rate or low temperature superplasticity at elevated temperatures [2,3]. It has been reported recently that ultr...
متن کاملWeldability Investigation of Fine-grained S1100ql Steel
I. Samardžić, Faculty of Mechanical Engineering Slavonski Brod, Croatia, A. Ćorić, Bratstvo, Novi Travnik, Bosnia and Herzegovina, M. Dunđer, Department for Polytechnic, University of Rijeka, Croatia. This paper presents the results of weldability investigation on welded joints made of fine grained high-strength S1100QL steel. The investigations are performed on two welded plates by HV 10 hardn...
متن کاملProcessing of Fine-Grained DP300/600 Dual Phase Steel from St12 Structural Steel by the Thermo-Mechanical Processing of Cold Rolling and Intercritical Annealing
The effect of microstructural refinement and intercritical annealing on the mechanical properties and work-hardening response of a low carbon St12 steel was studied. It was revealed that intercritical annealing of the ferritic-pearlitic sheet results in the formation of a coarse-grained DP microstructure with discrete martensite islands normally formed in place of pearlitic colonies, which resu...
