(8.94% Al, 0.70% Zn, 0.22% Mn, 0.02% Si, balance Mg) (mass fraction) were used as the matrix alloys. The beta-SiC particles with the average diameter of 50 nm were used as the reinforcing particles... a SiC nanoparticle and the magnesium matrix. The EDS spectrum of the interface is shown in Fig.5(b). The peaks of Si and C indicate the presence of SiC and the peaks of Mg, Al and Zn are attributed......

Received 6 December 2010; accepted 4 May 2011 Abstract: In order to study the self tempering effect on the solidification of Al-Si alloy, a setup was designed to conduct experiments. The characters of β.... Key words: β phase; Al-Si alloy; self tempering effect; Brinell hardness 1 Introduction Al-Si alloy is the most widely used aluminum alloy [1-2] in the manufacturing of the engine parts of cars......
structural parameters of the metal matrix composite, including particulate shape and distribution do not influence the elastic modulus. A prediction model for the elastic modulus of particulate reinforced metal matrix Al composite was developed and improved. Expressions of rigidity and flexibility of the rule of mixing were proposed. A five-zone model for elasticity performance calculation of the composite......
