Background:
Dr. Krishanu Biswas, Professor at the Department of Materials Science and Engineering at
IIT Kanpur has made significant contribution towards understanding of the several important
scientific and technological aspects of metallurgy and materials engineering. The research
work performed by him ranges from development of hard low friction wear-resistant coating
for coating applications , complex concentrated alloys (CCAs) including high entropy alloys
and entropy-stabilized ceramics, novel processing of ceramic composites, understanding the
alloying behaviour at nanoscale, development of alloy catalysis for hydrogen energy. His
recent research activities involve research on sintering of nanomaterials, nanocrystalline high
entropy alloys (HEAs), ionic nanoparticles, 2D materials etc. He has published over 125
papers in international repute and peer reviewed journals and delivered 40 invited talks in
different national and international conferences. Recently, he as co-edited a special issue on
“Nanocrystalline High Entropy Materials: Processing Challenges and Properties” in J.
Materials Research, published by Materials Research Society, USA. He has also signed
contract with Springer Nature to write a book on “High Entropy Materials: Processing,
Properties and Application”, to be published by December, 2019. He has completed 12
projects and currently 4 other projects are under progress. He could garner total funding to
the tune of 6,00,000,00 (US$8,50,000) in a span of 11 years. The projects include small
projects from Indian Space Research Organization (ISRO) and Indian National Science
Academy (INSA) to bigger projects from Department of Science and Technology (DST),
Department of Bio- technology (DBT), Board of Research on Nuclear Sciences (BRNS). He
has been actively involved in industrial consultancy with various companies, including MKU
Ltd, Kanpur, Tata Steels, Vardhaman Steels etc. Currently, 2 post doctoral fellow, 7 Phd
students, 3 MTech students, 2 project staffs and several B.Tech students working on different
research problems. 8 Phd students and 30 M.Tech students and large number of B.Tech
students have completed their degree under his supervision. He has international
collaboration with Japan, Taiwan, Germany, Sweden, USA. He teaches extensively at IITK
on variety of subjects including, Phase Equilibria, Manufacturing Processes, Phase
Transformations, Process Metallurgy, Solidification Processing etc. He has developed several
important web-based courses on NPTEL forum, including Phase Diagrams and Phase
Transformation in Materials. He has received a number of awards, fellowships and
professional reorganization from various organizations, notable ones being INSA Young
Scientist, Metallurgist of Year, Sri Ram Arora Award from TMS, USA, Young fellowship
from Global Young Academy, fellowship from West Bengal Academy of Science and
Technology etc. He serves in the editorial board of several international journals.
Abstract:
Multicomponent complex concentrated alloys (CCAs) are the newly discovered metallic cocktails and novel
entropy stabilized multicomponent ceramic, predominantly stabilized by configurational entropy of mixing.
It has expanded the field, opening up new vistas of exciting research on these materials. This field has
recently emerged as one of the most fascinating and challenging areas of materials research. In our research
group, integrated computational materials engineering (ICME) framework consisting of detailed CALPHAD
(CALculation of PHase Diagram) modeling and experimental investigation have been carried out to design
both equiatomic and non-equiatomic composition exhibiting thermodynamically stable single-phase FCC or
BCC. The major thrust involves establishing a robust thermodynamic based technique to design and develop
both equiatomic and non-equiatomic single phase alloys, thereby adopting accelerating the materials design
of multi-component systems. The use of integrated computational materials engineering (ICME) framework
consisting of detailed CALPHAD (CALculation of PHase Diagram) modeling and experimental investigation
have been carried out.
