Mechanical Property Evaluation of Electrodeposited Nanocrystalline Metals by Micro-testing
Electrodeposition is a very important technology in the fabrication of micro-compo‐ nents for micro-electro-mechanical systems (MEMS) or integrated circuits. Evalua‐ tions of the materials used in these devices as 3D components should be conducted using micro-sized specimens due to the sample size effect on the practical use of the components. Nanocrystalline metals could be deposited using an ...
متن کاملDifferences in the mechanical properties of calcaneal artificial specimens, fresh frozen specimens, and embalmed specimens in experimental testing.
BACKGROUND Artificial calcanei, fresh-frozen cadaver specimens, and embalmed cadaver specimens were compared in experimental testing under biocompatible loading to clarify the biocompatibility of artificial calcaneal specimens for implant testing. METHODS Two different artificial calcaneal bone models (Sawbone, Pacific Research Laboratories, Vashon, WA, and Synbone, Synbone Inc., Davos, Switz...
متن کاملA Novel Piezo-Actuator-Sensor Micromachine for Mechanical Characterization of Micro-Specimens
Difficulties associated with testing and characterization of materials at microscale demands for new technologies and devices that are capable of measuring forces and strains at microscale. To address this issue, a novel electroactive-based micro-electro-mechanical machine is designed. The micromachine is comprised of two electroactive (piezoelectric) micro-elements mounted on a rigid frame. El...
متن کاملFabrication and microstructure control of nanoscale mechanical testing specimens via electron beam lithography and electroplating.
It has been demonstrated that the mechanical properties of materials change significantly when external dimensions are confined to the nanoscale. Currently, the dominant fabrication method for mechanical testing specimens with nanometer dimensions is by using focused ion beam (FIB) milling, which results in inevitable Ga(+) induced damage to the microstructure. Here, we report a FIB-less fabric...
متن کاملMechanical Behavior of Concrete, Made with Micro-Nano Air Bubbles
Nano materials have been widely used in laboratory and industrial scales in order to improve various properties of concrete and concrete mixture. The mainstream practice of the researches in this field is to add metallic nano-particles into the concrete mixture. The present research focuses on adding Micro-Nano Air Bubbles (MNAB) into water before mixing it with aggregate and cement mixtures. I...
