Book excerpt: The microstructures of both martensite and bainite, although sharing some common features, depict a plethora of subtle differences that made them unique when studied in further detail. Tailoring the final properties of a microstructure based on one or the other as well as in combination with others and exploring more sophisticated concepts, such as Q&P and nanostructured bainite, are the topics which are the focus of research around the world. In understanding the key microstructural parameters controlling the final properties as well as definition of adequate process parameters to attain the desired microstructures requires that a proper understanding of the mechanism ruling their transformation and a detailed characterization first be acheived. The development of new and powerful scientific techniques and equipment (EBSD, APT, HRTEM, etc.) allow us to gain fundamental insights that help to establish some of the principles by which those microstructures are known. The developments accompanying such findings lead to further developments and intensive research providing the required metallurgical support.

It addresses applications of classical physical metallurgy, and the need for new modelling approaches, both on the analytical viewpoint and on the simulation side.
Download or read book Kinetics and Microstructural Evolutions During the Tempering of Martensitic and Nano bainitic Low Alloyed Steel written by Steve Gaudez and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nano-bainitic steels represent a new class of alloys, whose microstructure consists of nanostructured bainitic ferrite formed at low temperature with a high amount of retained austenite leading to a high ductility and high tensile strength of the steel. Formation of nano-bainite has been studied thoroughly in literature as well as tempering of nano-bainitic steels. More recently it has been shown that adding carbide forming elements such as V and Mo increases the resistance to softening and hence the mechanical properties of nano-bainite at moderate temperature. Investigating the secondary carbide precipitation inside a nano-bainitic microstructure is thus necessary to optimize the thermal treatments for this promising new class of steels. Three initial microstructures of the same steel composition are investigated: martensite, martensite + retained austenite and nano-bainite. Studying the more conventional case of martensite has served as a basis to better understand the microstructure evolutions inside the nano-bainitic steel. The microstructural evolutions during the tempering were followed by complementary experimental techniques including dilatometry, in situ high energy synchrotron X-ray diffraction (HEXRD), conventional and high resolution TEM. The sequence of carbides precipitation and dissolution (transition-iron-carbides, cementite, and alloyed carbides) both during heating and holding is shown similar for the three initial microstructures. The kinetics are similar as well as cementite chemical composition and size distributions of cementite and alloyed carbides. It has been shown too that the three microstructures present a high retained austenite stability. Moreover, the analyses of the lattice parameters evolutions all along the tempering treatment associated with carbon mass balances have allowed to better understand the carbon distributions between carbides and matrix phases. The nucleation and growth model from a previous work was upgraded to take into account secondary precipitation and different new features (e.g. para-equilibrium interface condition for first stage of cementite growth, etc.). This model predicts the kinetics of precipitation, the particle densities and size distributions as well as matrix and carbides mean composition for different tempering conditions. Apart from the comparison with the experimental results that is discussed, it allowed to interpret the similar tempering behaviour for the three initial microstructures.

Book excerpt: This is the third edition of the book, much expanded to include and incorporate important developments in the subject over the last fifteen years. The book represents a comprehensive treatise on all aspects of the bainite transformation, from the choreography of atoms during the phase change to length scales that are typical of engineering applications. The alloy design that emerges from this explains the role of solute additions, and the pernicious effects of impurities such as hydrogen. The picture presented is self-consistent and therefore is able to guide the reader on the exploitation of theory to the design of some of the most exciting steels, including the world’s first bulk nanostructured metal.
