(Mech.) degree from Birla Engg. College, Pilani in 1956 and received training in Mechanical Maintenance of Steel Plants in USSR. Shri Jain began his career at Bhilai Steel Plant of the then Hindusthan Steel Limited in the construction, maintenance and operation departments. Shri Jain rose to the position of Chief Mechanical Engineer and later of General Superintendent. He was elevated as the Chief Executive of the plant in 1975. He continued in this position till 1980 before being appointed as the Chairman-cum-Managing Director of Heavy Engg. Corporation. Shri Jain was deputed as Chairman-cum-Managing Director of Coal India Ltd in November 1982. Shri Jain finally held the position of Chairman of Steel Authority of India Limited. Late S R Jain (1934 – 2019) A very active technologist, Shri Jain had also served in the boards of different IIM President 1988 - 1989 organisations, e.g., MECON, Central Coal-fields Limited, Belpahar Refractories Limited, Almora Magnesite Limited, Hindustan Zinc Limited, Bharat Aluminium Co. Limited and Birla Institute of Technology, Ranchi. Shri Jain had been associated with IIM for over two decades. He was elected as Vice-President of the Iron & Steel Division in 1986, and became President of IIM during 1988-89. Dr. Kamla Prasad Singh left for his heavenly abode on 31st January 2019. Dr. Singh was a physical metallurgist having expertise in thermodynamics and corrosion. Dr. Singh joined IIT Kanpur in 1963 as Assistant Professor in the Metallurgical Engineering Department, was head of the Department from 1972 to 1977. Dr. Singh, a life member of IIM was instrumental in establishing the IIM Kanpur Chapter. He was a technocrat and able administrator. IIM Kanpur Chapter is deeply indebted to his contributions to the Metallurgical society. Dr. Kinkar Prosad Gupta breathed his last on 12th March 2019. He was a passionate experimental physical metallurgist. Dr. Gupta joined IIT Kanpur as Assistant Professor in 1963 in the Department of Metallurgical Engineering. He was head of the Department from 1967 to 1972, head of ACMS (Advanced Center for Materials Science) from 1976 to 1982, and head of Materials Science Program from 1982 to 1987. Dr. Gupta was a life member of IIM. IIM Kanpur Chapter will always be indebted to him for his kindness, mentorship and inspiration. ********* EDITORS CORRESPONDENTS Dr Manojit Dutta Sri S K Basu (Kolkata) Prof J Dutta Majumdar Dr Chiradeep Ghosh (Jamshedpur) Dr R Sandhya Sri Rishabh Shukla (Pune) Dr R Raghavendra Bhat Dr N Eswara Prasad Sri N K Kakkar (Delhi) Prof Sudhanshu Shekhar Singh Sri M N V Viswanath (Hyderabad) Dr Mithun Palit Vol.23 No.1 JANUARY 2020 Vol.23 No.1 JANUARY 2020 3 IIM METAL NEWS G D Birla Gold Medal Lecture 2019 Joining of Advanced Materials for Defence Systems G Madhusudhan Reddy Outstanding Scientist and Associate Director, Defence Metallurgical Research Laboratory, Hyderabad E-mail : [email protected] Abstract Keywords : Fusion welding, solid-state welding, dissimilar Metal joining processes consisting of fusion welding, metal welds, ballistic resistance, microstructure. solid state welding, brazing and soldering are employed 1. Introduction to join many of materials in similar and dissimilar metal Material joining encompasses fusion welding, solid state combinations. Many applications of conventional and welding, brazing and soldering. In fusion welding the modern engineering materials are limited by their ability to materials undergo melting and subsequent solidification. be joined. Steels constitute the most widely used category Fusion welds are prone to segregation, porosity and of metallic materials for defence hardware. Availability of solidification cracking. Segregation influences post new steels with increased strength and toughness as a result solidification phase transformations. The extent of of innovative improvement over the last few decades, has these changes is dependent on weld thermal cycle and aided the defence hardware designer to achieve improved the alloy’s response to the thermal cycle. Segregation, reliability. Cr-Mo, Ni-Cr-Mo and Si-Mn steels are some of porosity, solidification cracking and solid state cracking the steels employed for armour applications in battle tanks as are the problems associated with fusion welding. Some of well as personnel armour. The weldments of these steels are these problems need to be addressed during the course of required to exhibit resistance to projectile penetration and material development, as these are composition dependent. also should have the ease of fabrication.
