: Effects of the volume fraction and the size of crystallized alumina silicate short fibers as well as heat treatment processes on micro-yield strength(MYS) of Al2O3-SiO2(sf)/Al-Si metal matrix composite... of MMC decreases with the increase of volume fraction and length of the alumina silicate short fibers in the metal matrix composite, respectively. MYS of quenched Al2O3-SiO2(sf)/Al-Si MMC......
[4]. Up to now, less research focuses on magnesium alloy matrix composites reinforced with alumina silicate short fibers than aluminum alloy matrix composites[5-6]. In this study, the interface... with alumina silicate short fibers was evaluated, which will provide theoretic gist to farther investigation in the field. 2 Experimental Alumina silicate short fiber preform was made using Al(H2PO4)3......
that the in situ alumina fiber can be developed in Ti-Al matrix with the Ti/Al mole ratio of 1:2-1:7, and the addition of rare earth powders can improve the dispersion of the fibers in the matrix and increase the length-to-diameter ratio of the fibers. Key words: rare earth; additives; alumina fiber; intermetallic composite; microstructure 1 Introduction Reinforcing intermetallics with fiber is one......
