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 ...

Soil pollution generates diseases, hunger, and agricultural problems. Porous recycled glass beds were produced to study the feasibility of using them for polluted soil filtering. This research discusses structural and ...

Aluminum alloys containing 2 and 4 wt.% copper reinforced with aluminum borides were successfully fabricated by squeeze casting employing squeezing pressures up to 62 MPa. The distribution of reinforcements in the composites ...

A novel aluminum matrix composite reinforced with ceramic particles of AlB2 obtained through a cast process at temperatures below 800°C using commercial alloys of aluminum-boron (5 wt%. B) and aluminum-copper (33.2 wt%. ...

In this research, centrifugal casting has been used to investigate the influence of casting parameters and chemical composition on the manufacturing of functionally graded Al-2 wt. %B-6 wt. %Mg and Al-2 wt. %B-6 wt. %Cu ...

The present thesis focuses on the fabrication of aluminum wires by adding XB2 nanoparticles into an aluminum matrix, where X is a transition metal: Nb, Mg and Zr. The incorporation of aluminum in the XB2 particles is ...
