1Microstructure and properties of ZL205 Alloy显示文摘The microstructure, precipitate type, precipitate distribution and tensile strength of a ZL205 alloy, beforeand after ageing treatment, have been studied by means of optical microscopy and transmission electron microscopy.The results showed that the as-cast microstructure of the alloy was made up of α-Al and eutectic phase distributedat the grain boundaries. During ageing treatment, the tensile strength increased at first and then reduced with time,and the highest ultimate tensile strength was found to be around 488.2 MPa.Mi Guofa Wang Kuangfei Gong Haijun Wang Hongwei Zeng Songyan 2008China Foundry2008,5,1:6
2MICROSTRUCTURE AND PROPERTY OF Al/TiC COMPOSITES PREPARED BY REACTION SYNTHESIS显示文摘A novel in-situ process-Reaction Synthesis has been used to fabricate Al/TiC compos-ites,the phase constitute,microstructure and mechanical property of the Al/TiC composite have been investigated by the use of XRD and SEM.It has been shown that the reaction synthesized TiC particu-late is submicron in size(about 0.1~0.8μpm),spherical in shape and smooth in surface.In macrostruc-ture the distribution of the TiC particulate in matrix is homogeneous,but in micostructure there is micro-segregation of the TiC particulate at the intergrannular.The cast structure become fine because of the existence of the TiC particulate.In addition«with the increasing of weight percentage of TiC partic-ulate in alloy,the yield strength and ultimate tensile strength of the composite increase significantly«e.g.at 15%TiC,117% and 103% increase respectively,in the same time the elongation of the composite is still more than 4.5%.In the end,the analysis has been done by SEM on the fracture morphology of the composite.The results show that the fracture is ductility,and mainly because of the cluster of TiC particulate to intergrannular and the synthesis of bar morphology Al_(3)Ti.Zhang Erlin Zeng Xiaochun Zeng Songyan Li Qingchun 1996Transactions of Nonferrous Metals Society of China1996,6,1:3

9Microstructure Characteristic of In-situ Ti/TiC Composites显示文摘TiC reinforced titanium composites has been produced with different Al content and C content by XDTM. The results have shown that TiC particles are of two different morphologies f coarse dendritical primary TiC and short bar-shape eutectic TiC. Al content has great effects on the morphology of TiC. With the increasing of Al content, the morphology of primary TiC changes from coarse developed dendrite into short bar-shape or plate--shape TiC with 35%Al. Meanwhile, the structure of the matrix changes from single Ti to Ti and Ti3Al, and to Ti3Al and TiAl. However, the C content has no influence on the microstructure of matrix. When the C content is less than 1.2%, the dendrite TiC disappears and only short bar-shape or plate-shape TiC exists in the composites. In addition, the effect of he3t treatment on the morphology of TiC has also Studied.Bo YANG Beijing institute of Aeronauticul Materials, Beijing 100095, China Erlin ZHANG Yunxue JIN Zhaojun ZHU and Songyan ZENG National Key Lab. of Precision Hot Processing of Metals, Harbin institute of Technology, Harbin 150001, China 2001Journal of Materials Science & Technology2001,17,1:1
