Effect of interfacial characteristics on the failure-mechanism mode of a SiC reinforced A1 based metal-matrix composite

Processing of ultra-high strength SiCp/Al–Zn–Mg–Cu composites

“…Due to the obvious differences in properties between SiC and matrix alloy, such as elastic modulus, etc., the shearing stress existing at the interfaces will be enhanced with the increasing of the exerted stress. Once the shearing stress value exceeds the upper limit of the bonding strength, the interface debonding phenomenon between SiC and matrix will occur (Gupta et al, 1997). From Fig.…”

Preparation, microstructures and deformation behavior of SiCP/6066Al composites produced by PM route

“…Studies on the fracture mechanism of PRMMC have indicated that the particle fracture dominates the rupture of the composites reinforced by large particles (i.e., d > 20 m), while the interfacial debonding plays a critical role in the case of small reinforcements (i.e., d > 10 m) (Chen and Tokaji, 2004;Gupta et al, 1997;Nie and Basaran, 2005). However, the fracture surfaces in Fig.…”

Mechanical Properties of Metal Al/SiC and AlCu/SiC Metal Matrix Composites (MMCs)

“…In this paper, we report Al matrix and AlCu composites reinforced with silicon carbide (SiC) particle. It's believed that the hardness and meling point will improve significantly [6][7][8][9][10]. Microstructure and mechanical properties of Al/SiC and AlCu/SiC were characterized systematical.…”
