Abstract

"As the demand for new materials grows in the world, it is important to create materials that can give optimal performance for a specific application. Micro- and macro- structural features are important elements in designing materials that satisfy user-defined property requirements.

To develop the vision of "Materials by Design," the first paper presents an approach to develop a synergistic material for high efficiency structural applications. An approach is presented to optimize the macrostructure of the beam made specifically to take compressive loads. The synergistic beam is created to exceed the modulus given by the rule of mixtures. In the second paper, a methodology to tailor the microstructure to create a high strength high conductivity alloy is presented utilizing the existing theoretical, phenomenological, and empirical models. Only the empirical models were determined by performing reverse engineering of the high strength and high conductivity alloy, PD-135. In the third paper, an approach to optimize the maximum reduction possible to avoid wire breaks in the wire drawing process is presented utilizing finite element modeling.

The effort in this thesis deals with replacing the experimental approach of designing materials and processes with the computational approach, which optimizes the performance of processes and materials"--Abstract, page iv.
