“…MgO formed at the matrix/reinforcement interface can provide a barrier for diffusion of Si,C and Al for the composite containing less than 10 vol.%SiC. However, the formation of Al 4 C 3 is inevitable for the Al-14%SiC composite (Xiong et al, 2010).…”

“…For example, SiC p reinforced AMCs are used for engine piston, and heat sink [8,9]. Compared with traditional micron-sized SiC p /Al composites, the higher tensile strength and good ductility of the nano-sized SiC p /Al composites entitle them to have more competitive ability for advanced structural applications such as in automotive and aerospace industries and the military [10]. In the past decades, several processing techniques have been developed for fabricating Al matrix composites reinforced with nano-sized particles such as high-energy milling, powder metallurgy, and nano-sintering, and liquid-state solidification processing (e.g., stir casting) [11][12][13][14][15][16][17][18][19].…”

Abstract:The nano-sized SiC p /Al-Cu composites were successfully fabricated by combining semisolid stirring with ball milling technology. Microstructures were examined by an olympus optical microscope (OM), field emission scanning electron microscope (FESEM) and transmission electron microscope (TEM). Tensile properties were studied at room temperature. The results show that the α-Al dendrites of the composites were strongly refined, especially in the composite with 3 wt. % nano-sized SiC p , of which the morphology of the α-Al changes from 200 µm dendritic crystal to 90 µm much finer equiaxial grain. The strength and ductility of the composites are improved synchronously with the addition of nano-sized SiC p particles. The as-cast 3 wt. % nano-sized SiC p /Al-Cu composite displays the best tensile properties, i.e., the yield strength, ultimate tensile strength (UTS) and fracture strain increase from 175 MPa, 310 MPa and 4.1% of the as-cast Al-Cu alloy to 220 MPa, 410 MPa and 6.3%, respectively. The significant improvement in the tensile properties of the composites is mainly due to the refinement of the α-Al dendrites, nano-sized SiC p strengthening, and good interface combination between the SiC p and Al-Cu alloys.

“…And from the available literatures, the investigations about these effects on interfacial reactions are limited to providing the desired information and completed apprehension. In present investigation, the pressureless infiltration combining with ball milling and cold pressing technology was employed to fabricate the composites [21]. The objectives of the present study are to investigate on the effects of SiC volume fraction and aluminum matrix particulate size on interfacial reactions between SiC nanoparticulate and molten aluminum, and to achieve the significant information for controlling the interfacial reactions.…”
