Composites find important applications in a variety of fields since they combine the beneficial effects of both the components. Their properties can be further improved if the size of the reinforcement phase can be decreased and its volume fraction increased. Nanocomposites are relatively new materials in which the reinforcement and/or matrix is of nanometer dimensions. Conventional processing methods will not be able to fabricate these nanocomposites with large volume fraction of the reinforcement phase.  We have shown that mechanical alloying, a high-energy powder processing method, is a very suitable method to overcome this difficulty. The present talk describes our recent efforts in synthesizing and characterizing three different types of nanocomposites, viz., Al-Al2O3, TiAl-Ti5Si3, and MoSi2-Si3N4. The first describes our work to increase the volume fraction of the nanoreinforcement to about 50 vol.%, the second system describes our efforts in achieving increased plasticity, and the third describes our attempts to improve the fracture toughness of MoSi2.  


 Professor C. (SURYA) Suryanarayana is a Professor of Materials Science and Engineering at the University of Central Florida and is currently the Interim Chair of the Department of Mechanical and Aerospace Engineering. Prior to joining UCF in Orlando, he was a Professor of Metallurgy at Banaras Hindu University in Varanasi, India and also worked at the Wright-Patterson Air Force Base in Dayton, OH, University of Idaho, Moscow, and Colorado School of Mines in Golden, CO, USA.  His area of research is non-equilibrium processing of materials, with special emphasis on metallic glasses and nanostructured materials.

He has published over 350 technical papers in archival journals and authored/edited 21 books and conference proceedings. He is a member of the editorial boards of several international journals.  

Professor Surya has received many awards for his research contributions. Some of the important ones are the National Metallurgists’ Day Award of the Government of India, Science Academy Medal of the Indian National Science Academy, and Distinguished Alumnus award from Banaras Hindu University. Most recently, he was a Jefferson Science Fellow and Senior Science Advisor to the U.S. Department of State in Washington, D.C.

      Professor Suryanarayana is a Fellow of ASM International and also of the Institute of Materials, Minerals and Mining, London, UK.  He is one of the most cited researchers in the field of materials science and engineering.  According to Thomson Reuters, he is one of the top 40 researchers in the world in the field of materials science who achieved the highest citation impact scores for their papers published since January 2000.
