چکیده
In this study, Mg alloy-based composites (MMC: metal matrix composite) with uniaxially oriented continuous SiC fibers were fabricated using a low-pressure infiltration method. Next, the influence of Al particles as promoter on interfacial reaction between and alloy was investigated by means scanning electron microscopy (SEM) energy dispersive X-ray (EDX) analysis. presence particles, β-Mg17Al12 preferentially precipitated around fibers. The did not react directly remained bonded at fracture surface. contrast, in absence whisker-like Al4C3 observed fiber, phase consisting MgO Mg2Si circumferential part inside fiber. detachment occurred

critical period effects in foreign language learning:the influence of maturational state on the acquisition of reading,writing, and grammar in english as a foreign language
since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...

A Comparative Corrosion Study of Al/Al2O3-SiC Hybrid Composite Fabricated by Accumulative Roll Bonding (ARB)
In this study, the Al/Al2O3-SiC hybrid composite was produced by accumulative roll bonding (ARB). In the first and the second cycles, the particles were uniformly poured between the Al strips during each ARB cycle. In the subsequent cycles, ARB was repeated up to six cycles without adding the particles between the layers. After the total eight cycles, the particles were distributed uniformly wi...
