PROJECTS EXPERIENCE:

Steel Nitriding(Center for Heat Treating Excellence / WPI, January 2012 – August 2013 )

Characterized the nitrided layer to model and control the nitriding process parameters for realizing the accurate

process control. .

Prepared samples by cutting, mounting, grinding, polishing and etching pretreated steel rod.

Determined the compound layer thickness and nitriding depth using optical microscope.

Performed microhardness test of samples and analyzed the data to characterize nitrided layer.

Performed optical emission spectrometer (OES) test to measure the concentration of component elements in

different depth of nitrided samples.

Determined the phase characterization of nitrided surface using X-ray Diffraction analysis (XRD).

Stainless Blade Heat-treatment(Center for Heat Treating Excellence / WPI, March 2013 May 2013 )

Provide failure analysis on the blade and determine an alternate way of heat-treatment.

Prepared samples and measured Rockwell hardness and Vickers microhardness before heat-treatment.

Heat-treatment by heating, quenching, and tempering the samples.

Characterized by measuring Rockwell hardness and Vickers microhardness, determined the micostructure using

Optical microscope and scanning electron microscope (SEM).

PROFESSIONAL EXPERIENCE:

Metallurgist/Metallographer, (Center for Heat Treating Excellence, Worcester, MA, November2011 – October 2013)

Supported the process simulation and failure analysis by conducting a series of metallurgical experiments and

data analysis.

Representative/Visitor, (Mark One Co., Gaylord, MI, US, February 2014)

Visited Mark One Co., and inspected the GreenCleen steel washer.
