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 ...

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 ...

The tribological properties of a series of aluminum matrix composites reinforced with AlB2 particles developed for machinery parts intended for aerospace and automotive applications were evaluated. This thesis encompasses ...

Bio-ferroelectric composites have recently sparked intensive research in order to develop inexpensive and environmental electronic devices such as capacitors, transistors, and actuators. The present research involves the ...

The present work studies the effect of directional and rapid solidification on the distributions of borides reinforcements and mechanical properties of Al-B-Cu composites. To analyze the influence of these two manufacturing ...

The present study involves a novel method to synthesize under vacuum (AlMg)B2 – aluminum based composites. Incorporation of MgB2 into aluminum is a complex process because of the lack of wettability between both components. ...
