In this article, microstructural characteristics and mechanical properties of Al-Si-Cu/NCP composites were evaluated. Reinforced nanocomposites with 1 wt% nano-clay were fabricated by the method of the stir casting. Stirring times and temperatures were variable parameters to produce specimens. Consequently, the effect of a T6 heat treatment, which contained solutioning at 490 ºC for ...

Long association cortical fiber pathways support developing networks for speech and language, but we do not have a clear understanding of how they develop in early childhood. Using diffusion-weighted imaging (DWI) we tracked the frontal aslant tract (FAT), arcuate fasciculus (AF), and AF segments (anterior, long, posterior) in 19 typical 5-8-year-olds, an age range in which significant improvem...

Glassy carbon (GC) is an amorphous yet sp rich allotrope of carbon that has received a lot of attention as an electrode material in Li ion batteries. In this contribution we explore the microstructural, thermal and mechanical properties of GC derived from the pyrolysis of lithographically patterned SU8, which is the most common precursor polymer in CMEMS (carbon microelectromechanical systems)....

The tensile properties of Mg-3%Al nanocrystalline alloys were investigated at different test environment. Bulk nanocrystalline samples of these alloy was successfully prepared by mechanical alloying (MA) followed by cold compaction, sintering, and hot extrusion process. The crystal size of the consolidated milled sample was calculated by X-Ray line profile analysis. The deformation mechanism an...

If an ultrasonic signal is introduced into or generated within a structure, the state of the structure governs its propagation and detection. The assessment of the state of the structure can be affected by material properties, geometrical properties, environmental conditions, and measurement conditions. Because of the large number of possible properties and conditions, the quantitative ultrason...
