I am a metallurgist, interested in steels. My work pertains to research and developmental activities on steels. Specifically I use Electron optical instruments in characterisation of materials.In addition,I have carried out Failure analysis of wire ropes, turbine blade etc. Cr-Mo steels ; tempering & prior microstructure, Microstructural evolution in a single pass weld, Analytical Electron Microscopy and EELS
My doctoral dissertation is about Microstructural & Microchemical evolution in ferritic steels and weldments. The works were published in the following references:
1) J.Mat Sci., vol27, 1992, p5426
2) Acta Metall Mater., vol 43, 1995, p 2985
3) J. Nucl. Mater., vol 232, 1996, p 226
4) High temperature materials and processes, vol21,2002, p251-267
5) Trans.Indian Inst.metals, vol57, 2004, p253-64.
I have collaborated on the following structure-property correlation projects:
1) The micromechanisms of the LCF behaviour of Nimonic PE16 were understood thru extensive microscopy studies( Met Trans., vol 23A, 1992, p 1751) ;
2) Correlation of impact properties of simulated heat affected zones with microstructure ( Mat Charac. 48, 2002, p 55 & Mat Sci. Tech., 18, 2002, p 1195).
3) Microstructural evolution in laser treated surfaces of ferritic steels like 2.25Cr-1Mo steel, 9Cr-1Mo steel were understood ( J.Mat Engg.Perf., vol 10, 2001, p515; Proc of Int sym on Materials Ageing, Kalpakkam, India, 2000, P 502)
4) Failure analysis of locked coil wire ropes used in coal transporation ( Engg. Failure Analysis, vol10, 2003, p395-404)
My collaborative research work with Prof F.Hofer, FELMI, TU, Graz, Austria helped to study the nature and distribution of carbides in ferritic steel using EFTEM & EELS.
I had a fine collaboration during May-Aug.2004, with Dr Rafal Dunin Borkowski, Cambridge University which resulted in understanding the nature of carbides in ferritic steels using EFTEM & HAADF based electron tomography; and the effect of carbides on the magnetic nature of ferritic steels using Electron holography
Another collaboration I have is with Prof.K.Srinivasan, KREC, Surethkal, Karnataka, India. We regularly guide students of MTech for their project work.
I regularly join our local chapter of Indian Institute of Metals in conducting the annual event of national level Brahma Prakash memorial quiz on metallurgy and materials.
