Download or read book The Theory of Transformations in Metals and Alloys written by John Christian and published by Newnes. This book was released on 2002-12-10 with total page 1202 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work is a classic reference text for metallurgists, material scientists and crystallographers. The first edition was published in 1965. The first part of that edition was revised and re-published in 1975 and again in 1981. The present two-part set represents the eagerly awaited full revision by the author of his seminal work, now published as Parts I and II. Professor Christian was one of the founding fathers of materials science and highly respected worldwide. The new edition of his book deserves a place on the bookshelf of every materials science and engineering department. Suitable thermal and mechanical treatments will produce extensive rearrangements of the atoms in metals and alloys, and corresponding marked variations in physical and chemical properties. This book describes how such changes in the atomic configuration are effected, and discusses the associated kinetic and crystallographic features. It deals with areas such as lattice geometry, point defects, dislocations, stacking faults, grain and interphase boundaries, solid solutions, diffusion, etc. The first part covers the general theory while the second part is concerned with descriptions of specific types of transformations.

This book was released on 1967 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: By means of quantitative metallography and electrical resistance measurements, the incubation period (time to form a detectable amount of martensite) and the initial nucleation rate have been determined as a function of subzero reaction temperature and austenitic grain size in three iron-nickel manganese alloys containing 23-25 percent nickel, 2-3 percent manganese and 0.02-0.04 percent carbon. The isothermal martensitic transformation in these alloys has been found to occur over a wide temperature range of at least -1960 to -200 C, and the martensitic structure over the entire range is body centered cubic. The incubation period and nucleation rate as a function of reaction temperature at various austenitic grain sizes show typical C-curve kinetics. The true initial nucleation rate (not the apparent initial nucleation rate during the incubation period) is independent of grain size, and so the effect of grain size on the incubation period arises merely because of the size of the first-formed plates. Accordingly, it may be concluded that grain boundaries do not predominate as preferred nucleation sites for the martensitic transformation in the alloys studied. Calculations of the relevant thermodynamic functions indicate that 1 atomic percent manganese is thermodynamically equivalent to 1.6 atomic percent nickel in the driving force for the martensitic transformation. However, alloys of equivalent thermodynamic driving force exhibit striking differences in kinetic behavior due to slight differences in their manganese and carbon contents, suggesting that these elements reduce the potency of the embryos. The observed activation energies of the isothermal martensitic transformation are in very good agreement with the calculated activation energies based on a nucleation model. Moreover, in these alloys, the potency of the active embryos remains almost constant during the course of the isothermal transformation, notwithstanding the progressive generation of new embryos due to autocatalytic factors. The best fit between theory and experiment is obtained on the assumption that the number of pre-existing embryos in the parent austenite is 107 per cm3 . The probability of detecting such embryos by transmission electron microscopy is less than 1 in 105. The increase in the rate of isothermal martensitic transformation as a function of time has been shown to be due to the formation of new plates by auto catalysis, while the subsequent retardation is attributable to the partitioning of the austenite by the martensitic plates. The model used provides quantitative agreement with the course of the isothermal transformation up to 12 percent martensite.

Download or read book Handbook of Ferroalloys written by Michael Gasik and published by Butterworth-Heinemann. This book was released on 2013-05-04 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook gathers, reviews and concisely presents the core principles and varied technology involved in processing ferroalloys. Background content in thermodynamics, kinetics, heat and mass transfer is accompanied by an overview of electrical furnaces theory and practice as well as sustainability issues. The work includes detailed coverage of the major technologies of ferrosilicon, ferronickel, ferromolybdenum, ferrotungsten, ferrovanadium, ferromanganese and lesser known minor ferroalloys. Distilling the results of many years' experience in ferroalloys, Michael Gasik has assembled contributions from the worlds' foremost experts. The work is therefore a unique source for scientists, engineers and university students, exploring in depth an area which is one of the most versatile and increasingly used fields within modern metallurgy. All-in-one source for the major ferroalloys and their metallurgical processing technologies, cutting research time otherwise spent digging through old handbooks or review articles. In-depth discussion of the C, Si, Al-reduction, groups II-VIII of the periodic table, supporting analysis of metallurgical processing. Contemporary coverage includes environment and energy saving issues.
