This book explores diffusion in L12 and B2 structures of Ni3Al, Ni3Ge, Ni3Ga and NiAl, NiGe and NiGa and discusses Fe- and Co-based alloys in detail. These alloys of the VIIIA group elements are the basis of intermetallic compounds known as "super alloys," which are important in many technological high-temperature structural applications to improve mechanical strength properties such as creep.

Knowledge of diffusion behavior of intermetallic solids is critical, in particular in high temperature applications of material. Development of high temperature alloys depends on the understanding of diffusion in the aforementioned compounds. Therefore, this comprehensive book on diffusion in the iron group (VIIIA) based intermetallic compounds will be of interest to students, lecturers and researchers. For engineers working in the aircraft industry, this book will prove invaluable as it contains fundamental up to date information and basic knowledge on materials of their interest.

Deals with the basic problems of diffusion in Ni based intermetallics Considers diffusion in L12 and B2 structures of Ni3Al, Ni3Ge, Ni3Ga and NiAl, NiGe and NiGa with the possible inclusion of Ni3Si and NiSi Explores super alloys

Autorentext

Joshua Pelleg received his B.S. in Chemical Engineering Technion Institute of Technology, Haifa, Israel, M. S. in Metallurgy, Illinois Institute of Technology, Chicago, IL, USA and Ph. D. in Metallurgy, University of Wisconsin, Madison, WI. He is with Ben Gurion University of the Negev, Materials Engineering Department, Beer Sheva, Israel since 1970, was among the founders of the department, and its second chairman. Professor Pelleg was the recipient of the Sam Ayrton Chair in Metallurgy. His current research interests are diffusion in solids, thin film deposition and properties (mostly by sputtering) and characterization of thin films among them various silicides.

The previous book of this author, Diffusion of Ceramics, won a Texty award in 2015.
