Dual-phase steel DP steel is a high-strength steel that has a ferritic — martensitic microstructure. DP steels are produced from low or medium carbon steels that are quenched from a temperature above A 1 but below A 3 determined from continuous cooling transformation diagram. This results in a microstructure consisting of a soft ferrite matrix containing islands of martensite as the secondary phase martensite increases the tensile strength. Therefore, the overall behaviour of DP steels is governed by the volume fraction, morphology size, aspect ratio, interconnectivity, etc. These features render DP steels ideal materials for automotive-related sheet forming operations.

Steels: Microstructure and Properties

Steels represent the most widely-used metallic alloy, possessing a wide range of microstructures and mechanical properties. By examining the mechanical properties of steels in conjunction with microstructure this book provides a valuable description of the development and behaviour of these materials - the very foundation of their widespread use. Updated throughout and including new chapters on nanostructured steels, and new alloys and technologies for the energy and automobile industries, the book is clearly written and illustrated, with extensive bibliographies and real-life examples. An essential reference, both compact and readily comprehensive, for metallurgists and engineers in both industry and academia. Senior undergraduate students and postgraduates in materials science, physical metallurgy and mechanical engineering; Metallurgists and materials engineers in the steel industry. His research is concerned with the theory of solid-state transformations in metals, particularly multicomponent steels, with the goal of creating novel alloys and processes with the minimum use of resources.

Abstract: The purpose of this research is to quantify the effects of compositional and processing parameters on the microstructure and properties of dual phase steel produced directly by hot rolling and rapid cooling. Steels with the base composition of 0. Investigation was made to predict microstructure evolution and to correlate microstructure with processing parameters. The effects of the important microstructure parameters such as ferrite grain size, martensite volume fraction VM and morphology polygonal or fibrous on the tensile and impact properties are discussed. Multiple linear regression analysis of the ultimate tensile strength has shown that, increasing VM and martensite microhardness and grain refinement of ferrite are the major contributions to increase the strength of the steel.

This is a viewpoint paper on recent progress in the understanding of the microstructure—property relations of advanced high-strength steels AHSS. These alloys constitute a class of high-strength, formable steels that are designed mainly as sheet products for the transportation sector. AHSS have often very complex and hierarchical microstructures consisting of ferrite, austenite, bainite, or martensite matrix or of duplex or even multiphase mixtures of these constituents, sometimes enriched with precipitates. This complexity makes it challenging to establish reliable and mechanism-based microstructure—property relationships. A number of excellent studies already exist about the different types of AHSS such as dual-phase steels, complex phase steels, transformation-induced plasticity steels, twinning-induced plasticity steels, bainitic steels, quenching and partitioning steels, press hardening steels, etc.

Figure 1. Small gaps between atoms, called interstices, are where small elements like carbon and nitrogen fit. As the alloying increases, the straining in the atomic lattice increases, requiring more force to deform the workpiece, thereby increasing the strength. Any pure element is soft and ductile. This is why wedding bands are never made of pure karat gold.

Duplex stainless steels1 Developments, gradesand specifications1. The earliestgrades were martensitic and ferritic Fe-Cr steels, but quite soon theaustenitic Fe-Cr-Ni steels became the largest group. The growth ofthe austenitic alloys stemmed from their ease of production andfabrication, particularly welding.

Welded high-strength steel components have great potential for use in lightweight constructions or highly loaded structures. Based on electron backscatter diffraction and atom probe tomography, a concept for toughening and strengthening of all-weld metal samples was deployed. Furthermore, a higher average grain boundary misorientation was measured, which influences the toughness positively. An addition of vanadium caused the formation of vanadium-rich clusters, which increased the strength of the all-weld metal significantly. In lightweight constructions and for highly loaded components, high-strength steels are frequently used.
