“…Because manganese is segregated in the band structure, a considerable amount of austenite can transform to martensite during the cooling following the isothermal treatment, due to the increased hardenability of austenite. [17,18] Such a microstructure is more brittle than the one wherein hard phases are evenly distributed overall, and, thus, the formation of the band structure does not help to enhance the elongation. Consequently, the manganese content should be controlled at a lower amount in order to restrict the formation of the intercritically annealed for 5 minutes at 840 ЊC, at which the fraction ratio of ferrite to austenite is about 40:60, and then isothermally treated at 465 ЊC, 450 ЊC, and 430 ЊC for 1 and 10 minutes, respectively.…”

“…The higher fraction of retained austenite in the intercritical during plastic deformation, they do not contribute to ductility enhancement. As they can also increase the hardenability of cold-rolled steels, [17,18] it is likely that the microstructure turns into a structure mainly consisting of ferrite and martensite due to the martensitic transformation of austenite during cooling after the isothermal treatment. In this case, the eventual fraction of retained austenite is reduced, together with the occurrence of the deformation behavior of a dual-phase structure; thus, a higher strength can be expected but not an improved elongation.…”

The main emphasis of this study has been placed on understanding the effects of manganese and silicon additions and of heat-treatment (intercritical annealing and isothermal treatment) conditions on the microstructures and mechanical properties of 0.15 wt pct C transformation-induced plasticity (TRIP)-aided cold-rolled steel sheets. The steel sheets were intercritically annealed and isothermally treated at the bainitic region. Microstructural observation and tensile tests were conducted, and volume fractions of retained austenite were measured. Steels having a high manganese content had higher retained austenite fractions than the steels having a low manganese content, but showed characteristics of a dual-phase steel such as continuous yielding behavior, high tensile strength over 1000 MPa, and a low elongation of about 20 pct. The retained austenite fractions and mechanical properties varied with the heat-treatment conditions. In particular, the retained austenite fractions increased with decreasing intercritical annealing and isothermal treatment temperatures, thereby resulting in the improvement of the elongation and strength-ductility balance without a serious decrease in the yield or tensile strength. These findings suggested that the intercritical annealing and isothermal treatment conditions should be established in consideration of the stability of austenite and the solubility of alloying elements in the austenite formed during the intercritical annealing.

“…The system is also well characterized in terms of both microstructure and mechanical properties [13,14,18,25,44,45]. In addition, it was shown that a wide range of morphologies and mechanical properties could be produced from a single alloy through appropriate thermal processing [14,45], thus allowing for a more thorough and consistent investigation with fewer changes in alloy composition.…”

ABSTRACfThis thesis is concerned with the first (to the author's knowledge) attempts to utilize the properties of low carbon dualphase steels to produce high strength wire as an alternative to existing practice using pearlitic medium to high carbon steels.This goal to design a dual-phase steel suitable for drawing into high strength wire necessitated a study of the relationships between the microstructure and properties of undrawn rod and rod drawn into wire. and of the deformation of dual-phase steel at . ;. large strains.Dual-phase steel was selected for this study because of its pronounced strain hardening rate and superior formability. These properties permit dual-phase steel to be drawn to large strains and high strengths. The alloy composition and processing are ii generally quite simple and they can be varied to produce a wide range of structures and mechanical properties to fit specific applications.Dual-phase microstructures of several different martensite volume fractions, particle shapes, particle sizes, carbon contents and crystallographic relations with the ferrite matrix were studied. It was found that good mechanical properties could
