Abstract
Oxidation phenomena play a critical role in high temperature metallurgical processing and the performance during life cycle of components made of both high and low alloy steels. Therefore, the development of a precise experimental methodology to quantify oxidation processes is critically important. This report summarizes my experimental study of the oxidation behavior of high and low alloy steel, including kinetics of surface oxide layer formation and spallation. The focus of study was in determining the complex interactions between alloying elements in steel matrix and oxidation environment, composition and surface morphology of formed oxides. This report will also explore how the introduction of a low oxygen or high oxygen atmosphere along with the various temperatures affects the growth of scale. The developed methodology allowed me to investigate the real industrially produced steels with as cast and machined surfaces. Such investigations were limited before when used equipment permitted only small test specimens. This summary also discusses the methods of thermo-gravimetric analysis (TGA) and its use to quantify oxidation effects and what this data reveals about the relationship between oxidation and the conditions experienced by steel samples.
Biography
Clark Nguyen is a dedicated junior in Metallurgy with a passion for understanding the intricate properties and behaviors of metals. Clark's academic journey has been filled with many experiences and opportunities related to the field of material science. As an honor's student, his honor's projects like in PHY 2235 where he studied the concept of energy in materials or MA TH 3304, where he analyzed and reported on the use of differential equations and the Laplace transformation in metallurgy, specifically during heat transfer and phase transformation. Beyond his classwork academics, Clark is also an undergraduate researcher with the PSMRC project where he works on The Scale Research Project which is ran by Dr. Mario Buchely and Dr. Ron O'Malley. Here he has studied and worked on the effects of scale and the kinetics of steel as observed by thermogravimetric analytics.
