Abstract
Phase equilibria in the quaternary system Ti–Cu –Al –N are investigated using XRD, metallography and EDX, yielding the observation of 18 four phase spaces of the 850 °C isotherm. In the ternary boundary systems Ti– Cu–Al and Ti –Al –N, all previously reported phases are confirmed, but several tielines are newly determined. In the system Ti–N, the new ternary phase Ti3CuN dominates most phase fields. Based on thermochemical data of the binary boundary systems and the newly investigated or reinvestigated phase equilibria of the ternary boundary systems, a set of Gibbs energies for the solid phases occuring in the quaternary system is derived, which is used in combination with the quaternary experimental data to derive a large section of the isotherm for Ti –Cu –Al –N at 850 °C. The quaternary g-phase (Ti, Cu, Al)6N having the composition Ti3Cu2Al1N0.8 is found to be the only stable quaternary phase of this system. Several η-phases isotypic to Ti3Cu2Al1N0.8 are synthesized to explore the crystal chemistry effects of substitutions on different crystallographic sites.

CVD of Nonmetals
William S. Rees, jr. (ed.), VCH, Weinheim, Germany (1996)
ISBN 3-527-29295-0, hardcover, 424 pages, 149 figs., 46 tables, DM 238.–
The carcoal cave paintings of prehistoric art, based on soot, are, perhaps, one of the most ancient application of solid coating prepared from a gaseous precursor by means of a chemical transformation named Chemical Vapour Deposition (CVD). Today CVD forms the backbone of several modern technologies, i. e. the preparation of aerospace composites or protective over-layings of decorative jewelry with TiNx.
The book covers the area of preparation via CVD of non-metallic materials and, so, complement a series of books on CVD consisting of books on the growth of elemental metals via CVD edited by Kodas and Hampden-Smith and the epitaxial preparation of compound semiconducting materials by CVD presented by O’Brien and Jones.
The book starts with an introducting chapter by W.S. Rees, jr., presenting an overview of different methods of CVD techniques and the reaction kinetics CVD and thermodynamics in CVD. Chapter 2 by D.L. Schulz and T.J. Marks is focused on low- and high-temperature superconducting materials, i. e. the A15-superconductors (A3B phases), NbN films, and VBa2Cu3O7–x, as well as, Tl- and Bi-based high-temperature superconductors. Chapter 3 by T. Gerin and K.-H. Dahmen deals with the CVD of conducting materials, e. g. nitrides, halides, Indium-, Tin- and Zinc oxide systems.
Chapter 4 by G.S. Tompa presents CVD of semiconducting materials including group II-VI, III-V, IV-IV, carbides, oxides and organic materials.
Chapter 5 by A.R. Barron is focused on the CVD of insulating materials, e. g. oxides, nitrides, sulfides and fluorides.
Chapter 6 by W.J. Lackey deals with structural ceramics coatings and composites by chemical vapour infiltration of, e. g. carbon.
Finally, in chapter 7 by G.E. Kräuter and W.S. Rees, jr., describe CVD of various materials, e. g. oxides, sulfides, selenides and tellurides, nitrides, carbides, borides and complex ceramic materials.
The book is completed by a comprehensive glossary and index. All materials related chapters contain subchapters focused on basic aspects of the materials (crystal chemistry and structure) and their application giving an overview on the great diversity of materials in modern technologies. The various precursors for CVD of the different materials and reaction schemes are presented, as well as technical aspects, e. g. reactor design and different deposition techniques. Each chapter contains a comprehensive list of references, summing up to the amount of 1361 references of the entire book.
The book represents a useful reference to the practitiners in the field, as well as an excellent entry for the novice.
