This book gives a brief history of the development of Alloy 625 and a detailed account of its physical, mechanical, and corrosion properties. It also addresses different types of microstructural changes the Alloy 625 undergoes at intermediate temperatures; provides details of properties deterioration due to such microstructural changes; assesses the alloy damage during the in-service inspection of plants; and provides criteria for the damage evaluation for various destructive and non-destructive testing. It combines the industrial data and literature together in one place for damage assessment of service exposed Alloy 625 components. This book serves as a guide to practicing engineers in the industry interested in the use of Alloy 625 and in academia for students pursuing advanced courses in materials science. Alloy 625 is a versatile nickel-chromium-molybdenum alloy known for its unique combination of high strength, excellent fabricability and weldability, and outstanding corrosion resistance.

Dr. J.B. Singh, Head, Structure of Materials Section of the Mechanical Metallurgy Division of Bhabha Atomic Research Centre (BARC), Mumbai, is a leading expert in the areas of nickel-based superalloys and structure-properties correlations. He joined BARC in 1991 after completing an advance course in nuclear engineering with metallurgy as the specialization. He did his B.Tech. in Metallurgical Engineering from Indian Institute of Technology, Kanpur, in 1990, and obtained a Ph.D. from Indian Institute of Technology, Bombay, in 2002. Dr. Singh has an accomplished career demonstrating consistent success as a researcher and a teacher and has made significant contributions in the fields of phase transformations and deformation behavior of metallic systems. He has carried out decisive experiments to advance the understanding of microstructural evolution and micro-mechanisms of plasticity in advance alloys. He is Professor of Engineering Sciences, Homi Bhabha National Institute (HBNI), Mumbai, and has taught courses related to "Physical Metallurgy," "Plasticity and Strengthening Mechanisms in Crystalline Materials," and "Materials characterization." He has guided many students for their M.Tech. and Ph.D. dissertations. He has been a visiting scientist to CEMES, Toulouse, France (in 2003 and in 2004), University of Illinois at Urbana-Champaign, USA (2005-2007), Helmholtz-Zentrum Berlin, Berlin, Germany (2011), and Institut Laue Langevin (ILL), Grenoble, France (2012).
