This research seeks to characterize Al-Ce-based alloys processed via different routes. These production methods include powder-in-tube, gravity casting, and powder extrusion. Al-Ce alloys samples were made by gravity casting ...

The experimental work in this thesis is focused on the alloying effects of Mg and Si in Al-Ce base alloys. The alloys were gravity cast over a 20-point (or target chemical compositions) test matrix. X-ray diffraction, ...

The fabrication, characterization and testing of sputtering targets were completed for the deposition of hybrid composites. The chemical composition of the target specimens consisted of an aluminum-silicon matrix reinforced ...

Modern construction industry requires new technologies to comply with increasingly stricter environmental regulations. In particular, cutting back cement demand in concrete fabrication lowers carbon dioxide emissions caused ...

Accordingly, the present research sought a cost-effective alternative to repair structures and rescue equipment with better quality welding, for rapid restoration of areas affected by disasters. This study focuses on the ...

Al-Cu composites reinforced with diboride particles were fabricated by gravity casting. A thermomechanical analysis (TMA) system allowed studying hardness and creep behavior of the composites. The composite hardness was ...

The aerospace industry has focused on the development of high performance polyimide foams because these materials are known for their thermal and acoustic insulation properties. Tortuosity is defined as a parameter that ...

Chemical dealloying can be used to fabricate porous metals by removing one or more of the species out of an alloy. Generally, a corrosive electrolyte is used to selectively dissolve a noble element. Alloy concentration, ...

In the present research, atomic force microscopy (AFM) was used to characterize fracture surfaces of the AF1410, ultra-high strength steel, and a high strength AA7075-T6 aluminum alloy. Both materials are used by the U.S. ...

Most polymers by themselves have limitations due to their poor mechanical, thermal and electrical properties compared with metallic and ceramic materials. Therefore, to expand their range of applications these properties ...
