Stress-strain relationships applicable to elastic and plastic deformation, Mohr’s circle of
stress and strain, yielding criteria, dislocation theories, strengthening mechanisms, ductile

Research Contribution

Prof. Roy developed a state-of-the art research facility known as the ‘Materials Performance
Laboratory (MPL)’ to accommodate testing related to numerous funded research projects within the
Department of Mechanical Engineering. Most of these projects were aimed at evaluating the
metallurgical, mechanical and corrosion behavior of materials using numerous relevant techniques
for energy applications. MPL is well-equipped to study the effect of heat-treatment on the resultant
metallurgical microstructure and mechanical (tensile) properties of engineering metals and alloys at
ambient and elevated temperatures in the presence of an inert atmosphere. MPL is also capable of
evaluating the fatigue strength, creep deformation, creep-fatigue interaction, fracture toughness, and
crack initiation and growth-rate of engineering materials using fracture mechanics principles under
different loading conditions. Loading frames with furnaces have been installed to evaluate tensile
and fatigue properties, time-dependent deformation (creep) and stress-rupture behavior of structural
materials as functions of applied load/stress and temperature.

The susceptibility of many metallic materials and alloys to environment-induced degradations
including localized corrosion, stress corrosion cracking (SCC) and hydrogen embrittlement (HE) can
be evaluated in MPL using both conventional and electrochemical test methods. Environment-
assisted cracking behavior such as SCC and HE, which are of major concern to different energy-
related applications such as the nuclear power generation, oil and gas exploration, and geothermal
energy development, can be precisely evaluated under constant-load, constant-displacement (double-
cantilever-beam) and slow-strain-rate (SSR) conditions in different operating environments of
interest. The susceptibility of these alloys to localized corrosion (pitting and crevice corrosion) and
intergranular/transgranular attack can be evaluated by electrochemical polarization techniques at
ambient and elevated temperatures. In essence, this world-class research facility at UNLV is capable
of materials characterization as functions of numerous metallurgical, environmental and mechanical
variables related to many engineering applications. This research facility has been continuously
upgraded with new equipment till 2008.

Materials research pursued at UNLV under different funded projects has led to the development of
fundamental understanding on many relevant scientific and engineering phenomena involving high
performance metals and alloys for applications such as transmutation of spent nuclear fuel, disposal
of high-level radioactive waste, and generation of electricity and hydrogen (NHI/NGNP). A
significant number of journal articles and conference papers have resulted from these research
activities. UNLV has now emerged as a leading materials research university pioneering in the
following areas. Prof. Roy was honored with the ‘College of Engineering Outstanding Researcher
3
award for 2006-2007 Academic Year’, in recognition of his research contributions. Simultaneously,
he was internationally recognized as a ‘Fellow’ of the Institute of Materials, Minerals and Mining
(IMMM) of the United Kingdom in 2006.
