reinforced aluminum matrix composites were fabricated by the direct melt reaction technique in the Al-Zr-O system. Microstructures of the composites and crystal morphology of in-situ formed Al3Zr and Al2O3...; TG146.2 Document code: A 1 INTRODUCTION The attractive physical and mechanical properties of aluminum matrix composites (AMCs), such as high specific modulus, strength, and thermal stability......
; Abstract: 6061Al matrix composites reinforced by ZnO-coated Al18B4O33 whiskers were fabricated by a semi-solid mechanical stirring technique. The effects of ZnO coating on interfacial reaction between whiskers and matrix and the tensile properties of the composites were investigated. Tensile tests on composites were......
reduction reaction. The microstructure of the C/C-ZrC composites was also investigated. The composites exhibit an interesting structure, a coating composed of ZrC ceramic covers the exterior of the composite, and the ZrC ceramic is embedded in the pores of the matrix inside the composite. Key words: ZrC precursor; pyrolysis mechanism; precursor infiltration and pyrolysis; C/C-ZrC composites 1 Introduction......

, oxides ceramic particles are frequently applied to aluminum matrix composites due to its stability and inertia, wear resistance, and high temperature resistance [6]. Some researchers have proved that aluminum-matrix composites optimized with oxides ceramic reinforcement possess better mechanical and physical properties, which are extremely suitable for tribological parts by reason......
Thermo-physical Properties of Continuous Carbon Fiber Reinforced Copper Matrix Composites 黄俊波1,陈先有1,曹金华1 (1.Army Aviation Representative Office,109 mail box,Jingdezhen 333002,Jiangxi,China) 摘要:Continuous carbon fiber reinforced copper matrix composites with 70％(volume fraction)of carbon fibers prepared by squeeze casting technique have been used for investigation of the coefficient of thermal......

into copper matrix to obtain low CTE matching ceramic substrates and semiconductors. However, if volume fraction of reinforcement exceeds 40%, the composite fabricated by conventional powder metallurgy would... because it lessens the residual thermal stress induced during fabricating process[10]. The SiCp/Cu composites were fabricated by squeeze casting process. The CET difference between Cu matrix and SiC......
