Ph.D. Thesis:

Title:   Effect of Equal Channel Angular Extrusion on Microstructure   Mechanical Properties and Corrosion Behavior of Wrought AZ     Magnesium Alloys.       

   (NRB funded project- NRB/4003/PG/366-2015)

Supervisor: Dr. Narendranath S, Professor, Dept. of Mech., Engg. NITK-Surathkal.

Magnesium alloys are extremely good choice for engineering applications because of its light weight, high damping capacity and dimensional stability properties which are critical design parameters for machine essentials. Poor strength and low ductility of Mg alloys have been attributed. An effort to overcome these limitations through ECAP techniques was employed to obtain ultra-fine grain (UFG) structure leading to the strengthening of Mg alloys and nevertheless strength and sustainability of materials under different environmental conditions are also an important aspect. Hence, it is necessary to investigate the corrosion behavior of the equal channel angular pressed magnesium alloys. The present project investigates the grain refinement through equal channel angular press/extrusion and corrosion behavior of ECAPed sample before and after coating. Also, characterizations of the tested samples have studied through an optical microscope, scanning electron microscopy and XRD, EBSD and so on.

M.Tech. Thesis:

Title:   Development of Wire Electric Discharge Turning process using Wire-EDM and parametric optimization of process 

         parameters for INCONEL 718.

              (DST funded project- SERB-SB/S3/MMER/0067/2013)

Supervisor: Dr. Narendranath S, Professor, Dept. of Mech., Engg. NITK-Surathkal.

         The objective of this work was to develop Wire ED Turning by using Wire ED machine and to investigate the effects of Machining Parameters on MRR and surface roughness in Wire EDT process. In this process  INCONEL 718 Nickel based Super alloy was chosen for the experiments because of its growing application in the field of aerospace, chemical, Nuclear power plant and gas turbine engine parts. The optimization of Wire-ED Turning parameters such as Rotational speed, pulse on time, pulse off time, servo voltage, wire feed rate, flushing pressure have been analyzed on MRR, Surface roughness by using L18 mixed type Taguchi’s  Orthogonal Array experiments, ANOVA, Grey Relation Analysis and by analysis of mean(ANOM). In order to study surface integrity, SEM and Micro-hardness testes were carried out in different machining parameters and also a mathematical model is developed by using Buckingham’s pi theorem to analyze crater diameter on component after machining.
