(2015-04-20)This work investigates elevated temperature deformation in the nickel-based superalloy Haynes 230 and elastocaloric cooling in shape memory alloys. Three loading conditions were examined in the elevated temperature portion: ...
(2015-01-20)Reactive metals are routinely added in applications such as propellants and explosives to increase energy density and total energy output. These materials are also becoming useful in warhead casings compared to traditional ...
Advanced materials integration and thermal operation of heated microcantilevers and microcantilever arrays (2015-03-20)This dissertation presents the development and characterization of novel heated microcantilevers and microcantilever arrays for atomic force microscope (AFM) applications. AFM microcantilevers with integrated solid-state ...
(2015-04-13)Five axis micro-ball end milling has been shown as a viable option for machining complex free form surfaces with high aspect ratios and provide micron-scale tolerances. Unfortunately, due to the high fragility of the cutting ...
(2015-03-18)The acoustic emission resulting from the reciprocating motion of machinery parts, such as the movement of pistons and the intake/exhaust of gases in an automotive engine, or the pressure pulsation generated in compressors ...
