Gamma Titanium Aluminide Alloys von Fritz/Paul Appel

The first book entirely dedicated to the topic emphasizes the relation between basic research and actual processing technologies. As such, it covers complex microstructures down to the nanometer scale, structure/property relationships and potential applications in key industries. From the contents: * Constitution * Thermophysical Constants * Phase Transformations and Microstructures * Deformation Behaviour * Strengthening Mechanisms * Creep * Fracture Behaviour * Fatigue * Oxidation Resistance and Related Issues * Alloy Design * Ingot Production and Component Casting * Powder Metallurgy * Wrought Processing * Joining * Surface Hardening * Applications and Component Assessment

Fritz Appel has continued to play an active role in TiAl research since his retirement in 2006 as group leader of physical metallurgy. He obtained his Ph.D. in 1973 and his habilitation in 1987 from the Martin-Luther University in Halle, Germany. He spent six months in Japan on a JSPS fellowship in 1987, joining the GKSS Research Center in Geesthacht in 1990. Dr. Appel received the Tammann Award from the German Society for Materials Science in 1999 and the Charles Hatchett Award in 2002 from the Institute of Materials, London. He has published over 160 papers, given over 80 invited lectures and holds six patents in the field. Jonathan Paul has been a member of the Institute of Materials Research in Geesthacht since 1999. He obtained his Ph.D. from Manchester University in 1990, and after a year of postdoctoral research, moved to the Commissariat à l''Energie Atomique at Saclay in 1993. Between 1995 and 1997 he worked as a research fellow at GKSS, before being employed at the Defence Evaluation Research Agency (formerly known as the Royal Aircraft Establishment, now re-named QinetiQ) within the Structural Materials Centre in Farnborough. Dr. Paul received the Vanadium Award in 1995 and the Charles Hatchett Award in 2002, both from the Institute of Materials, London. He has co-authored and authored a number of publications and holds four patents. Michael Oehring works in the physical metallurgy group at the Institute of Materials Research in Geesthacht. He received his Ph.D. in 1988 from the University of Göttingen, Germany, where he remained until 1989, working in the area of field ion microscopy. He then joined the applied physical metallurgy group at GKSS, where he remained until 1993, before transferring to the group headed by Fritz Appel. Dr. Oehring received the Charles Hatchett Award in 2002 from the Institute of Materials, London, and has authored or co-authored over 100 papers as well as five patents.
