Applied Chemistry and Corrosion Laboratory, National Metallurgical Laboratory, Jamshedpur, India NML Jamshedpur is an Indian research center that functions under the aegis of Council of Scientific and Industrial Research. Advisor: Dr. Raghuvir Singh (Scientist E2) • Worked on Corrosion (Low temperature sensitization) of austenitic stainless steel. • Designed and optimized protocols for Laser processing of materials (Cladding, welding, heat treatment). • Hands on experience with several tools used for materials characterization. Worked on the following projects: 1. SSP 0524 - Low temperature sensitization in Austenitic stainless steel"- This project was funded by the Bhabha Atomic Research Center (BARC) Mumbai. Here, we studied various aspects that influence sensitization in austenitic stainless steel at low temperatures (300-400 C). I did the following tests: ASTM 262 (A to F), Dual loop electrochemical potentiokinetic reactivation (DL-EPR) test, Solution annealing, Heat treatment, Hardness measurement, Microstructure analysis and Degree of Sensitization (DOS) measurement. For the DL - EPR test, I used potentiostat made by Gamry Instruments. I also did creep and stress rupture tests. 2. SIP 0025 - Additive manufacturing: I worked on laser surface treatment (Cladding, Welding and Surface hardening) using diode laser (Model: ROFIN SINAR DL028Q). It was used for improving surface properties of steel by laser scan and fast quenching as well as by cladding with various metallic powders (Tungsten Carbide, Stellite)). This work resulted in one journal paper. I have been acknowledged for my effort in this paper.

Multi-Objective Genetic Algorithms and Genetic Programming Models for Minimizing Input Carbon Rates     
Published by (Steel Research International)
Authors: Rajesh Jha, Prodip kumar Sen, Nirupam Chakraborti.  Published February 04, 2014

Novel nature inspired strategies are used to construct models of Productivity, CO2 emission, and Si content of an operational Blast furnace and the optimum tradeoffs between the level of CO2 emission and productivity at different Si levels are computed and analyzed in detail. Also, comparisons are made with the results of a thermodynamic model and those from some commercial software.
