The following problem is addressed: ‘Can one synthesize microstructure evolution over a large area given experimental movies measured over smaller regions?’ Our input is a movie of microstructure evolution over a small sample window. A Markov random field (MRF) algorithm is developed that uses this data to estimate the evolution of microstructure over a larger region. Unlike the standard micros...

We have developed a 3-dimensional computer simulation tool to study the characteristics of microstructure evolution in damascene interconnects. This tool is based on the Monte Carlo method, and the characteristics of the microstructure evolution have a significant impact on the interconnect reliability. Our simulation results show that it may not be possible to obtain a bamboo microstructure th...

Complex microstructure changes occur in nuclear fuel and structural materials due to the extreme environments of intense irradiation and high temperature. This paper evaluates the role of the phase field method in predicting the microstructure evolution of irradiated nuclear materials and the impact on their mechanical, thermal, and magnetic properties. The paper starts with an overview of the ...

We study the time evolution in elastoplasticity within the rate-independent framework of generalized standard materials. Our particular interest is the formation and the evolution of microstructure. Providing models where existence proofs are possible is a challenging task since the presence of microstructure comes along with a lack of convexity and, hence, compactness arguments cannot be appli...

We present experimental and numerical results for nonlinear polarization evolution of femtosecond pulses during propagation in microstructure fiber. Numerical modeling shows that fiber dispersion permits a long interaction length between the components polarized along the two principal axes, thereby enhancing the effective nonlinear polarization evolution in microstructure fiber.

A variety of cast pyrometR 718 alloy microstructures result from processing of different diameters of industrial scale ingots for producing superalloy forgings used in aircraft turbine engine applications. The hot workability of these cast alloys will significantly depend on the cast microstructure. The current study is focussed on understanding the evolution of the cast microstructure during V...

in this study the synthesis of molybdenum oxide nano-whiskers with circular cross-section is performed. in some areas, it was observed that also some whiskers have open tips exhibiting their hollow structures. these whiskers have side dimensions ranging 2-5 μm with an average diameter in the nanometer rang. the structure suggested the vapor-liquid-solid growth mechanism (vls). scanning elect...
