Hi, I am Dr. T. K. G. Namboodhiri, retired Professor of Metallurgical Engineering, Institute of Technology, Banaras Hindu University, varanasi, India. Since my retirement in 2004, I am an Emeritus Professor at two new Engineering Colleges, Sree Buddha College of Engineering and Saintgits College of Engineering in Kerala, India. I hold a B.Sc (Metallurgical Engineering) degree from Banaras Hindu University and M.S. & Ph.D. degrees from University of Pennsylvania, Philadelphia, USA. My areas of interest are mechanical behaviour of materials,specially,environment-assisted fracture and hydrogen embrittlement,as well as corrosion and its prevention. I like the idea of free-access literature and am a regular visitor to Wikipedia. Currently I am working on an article on Hydrogen Damage in Metallic Materials for the wikipedia. Suggestions are most welcome. I may be contacted at tkg_namboodhiri@yahoo.com or tkgnamboodhiri@gmail.com
