Prior Research Experience
Bachelor’s Thesis at Direct Digital Manufacturing Laboratory, Georgia Tech, Atlanta (May 2015 – present)
Title: Quantitative Metallography Aided Experimental Characterization and Design-of-Experiment Based
Process Optimization for Single-Crystal CMSX-4® Ni-base Superalloy Processed Through Scanning Laser
Epitaxy (SLE)
Project guide: Prof Suman Das
•
Learned about additive manufacturing technologies that can be used for metals in general, and for Nibased superalloys in particular.
•
Understood the conditions that favour epitaxial growth of crystals, and how they can be utilized for
obtaining deposits that are microstructurally continuous with the underlying substrate.
•
Currently performing experiments as a part of a Design-of-Experiment based process optimization for
the single crystal Ni-based superalloy CMSX-4, to determine the best processing parameters for different
geometries.
•
The experiments are followed by sectioning of the sample and metallography. The obtained micrographs
are processed using a quantitative metallography image processing code, developed exclusively for this
process.
•
The final goal is to be able to develop a function that is able to predict the processing parameters for any
given geometry, such that a deposit with a good single crystal height can be obtained.
Summer internship at Manufacturing and Materials Technologies, GE Global Research, Bangalore (2014)
Title: Investigation of recrystallization due to compression straining in Ni-based superalloy GTD 444
Internship Supervisor: Dr. Sachin Nalawade
Manager: Dr. Sanjay Sondhi
1
•
Learned about Ni-based superalloys, with particular attention to Single Crystal (SX) and Directionally
Solidified (DS) superalloys that find application in Last Stage Buckets (LSBs).
•
Gained exposure to the scale of operations in the field of Gas Turbines and comprehended the importance
of the smallest positive change in properties with regard to efficiency and market dynamics.
•
Understood the importance of microstructure, and how subtle changes therein could result in large
changes in macroscopic properties.
•
Undertook an observational study of Solution Heat Treatments (SHT) and gained insight into its criticality.
•
Performed systematic metallographic analysis on the heat-treated samples in an effort to find recrystallized
grains. The investigation was performed under the optical microscope, although the SEM was also used
occasionally.
•
Analyzed and quantified micrographs using image processing techniques.
•
A report from the mentor is available at shashankhr.com/gecertificate.pdf.
Summer project at Department of Materials Engineering, IISc, Bangalore (2013)
Project guide: Prof. Praveen Kumar
•
Studied flow pattern formation due to electromigration and thermomigration (in Gallium).
•
Worked in the National Nanofabrication Facility at the Centre for NanoScience and Engineering, IISc
(CeNSE, cense.iisc.ernet.in).
•
Learned to use a Micro System Analyzer, an instrument used to visualize surface topography.
•
Gained experience with image and video processing techniques, and mathematical analysis tools.
