Alloy 625

Dr. Jung Bahadur 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).
