AFM studies on fractured surfaces of AF1410 steel and A7075-T6 aluminum alloy
(2006)
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. ...
Characterization of squeeze-cast AIB12/AI and AIB2/AI composites
(2009)
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 ...
Efectos de la deformación mecánica sobre compuestos de matriz de aluminio tratados térmicamente
(2004)
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%. ...
An experimental study of aluminum boride particles distribution in centrifugally cast AI/AIBx composites
(2009)
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 ...
Synthesis and characterization of (AlMg)B2- aluminum based composites and nanocomposites
(2007)
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. ...
Tribological characterization of Al-Cu-Mg-B composites subject to mechanical wear
(2009-12)
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 ...
Studies on directional and rapid solidification of Al‐B‐Cu composites
(2007)
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 ...
Fabrication and characterization of functionally graded Al/AlB2 matrix composites for high wear aerospace applications using centrifugal casting
(2006)
Functionally graded advanced composite materials contain reinforcement particles whose volume fraction varies continuously thereby bearing a non-uniform microstructure with continuously changing properties. Aluminum-based ...
