Research Contribution

Professor Chattopadhyay is primarily a Material Scientist and Electron Microscopist. His research aims at synthesizing newer materials through nonequillibrium processing and understanding their structure and stability at different length scales. The processing techniques utilized by him include techniques of rapid solidification and undercooling of the melt, mechanical alloying of solids, laser ablation and laser/electron beam processing. These efforts have also led to the discovery of decagonal and ordered quasicrystals, new metallic glasses for magnetic and structural applications and nanocomposites of metals and alloys. His current work includes synthesis of embedded multiphase nanoparticles and high temperature materials like silicides through nonequillibrium routes, thermoelectric materials and development of ultrahigh strength materials using multicomponent concentrated alloys. A significant amount of effort is currently directed to understand technically important processes like dissimilar welding and cladding where the system experiences a very large departure from equilibrium. His current research thrust revolves around developing new high temperature materials. As a foremost practitioner of the electron microscopy in the country, Professor Chattopadhyay utilized this tool elegantly in conjunction with other techniques to unravel the complex structure of the materials that he could synthesize in his laboratory. The discovery of decagonal quasicrystal, ordering in quasicrystals and complex crystals which are closely related to quasicrystals (known as approximant crystals) are a testimony to his novel approach and skill. He is widely known for his work on phase transformation of metal and alloys and in particular small particles. He is regarded as one of the leaders in the utilization of in-situ electron microscopy and his work on understanding the melting behavior of small particles of metals and alloys is highly regarded and extensively cited. Professor Chattopadhyay’s recent work include phase separation in liquid and glasses and in understanding the peritectic reaction in melt for which he has utilized host of techniques including levitational undercooling and recently microgravity in the first Indian microgravity experiment on board the India’s first recoverable SRE vehicle. Currently his group has made major contribution to understand the atomic level processes occurring at dissimilar joint interfaces and the mechanical behavior of bulk metallic glasses. Professor Chattopadhyay leads the Indian effort in microgravity research. He is currently spearheading a large energy program which includes a major consortium of Indian and American academic institutions and industry under the joint umbrella of US and Indian science agencies and another large Indian programme for developing efficient solar energy systems on behalf of Government of India and Government of Karnataka.

Awards and Honours

Recipient of the prestigious Shanti Swaroop Bhatnagar Award in 1995, he is also a recipient of The Medal of the Materials Research Society of India, the Birla Gold Medal of the Indian Institute of Metals, the National Metallurgist Award of Government of India for life time contribution to the metallurgical profession and the Life Time Achievement Award of the Electron Microscope Society of India. He is a fellow of all the science and engineering academies of the country including Indian National Science Academy (INSA), Indian Academy of Science (IASc) and Indian National Academy of Engineering (INAE). He is also a life fellow of the Indian Institute of Metals.
