rare earth(RE). The results indicate that, under Cd stress, the dry and fresh weight are increased by both the single element and mixed rare earth treatment, and the fastness of rape is improved.The single element of rare earth decreases the Cd content in rape roots and transmits Cd to the edible parts above the ground in which the alleviation effect of Ce is most significant.La treatment takes......
Article ID: 1003-6326(2005)06-1285-05 Effects of rare earth element Ce on solderabilities of micron-powdered Sn-Ag-Cu solder XUE Song-bai(薛松柏)1, YU Sheng-lin(禹胜林)2, WANG Xu-yan(王旭艳)1, LIU..., spreading ratio, wetting time, and melting point, were investigated for verifying the effects of rare earth element Ce on solderabilities of micron-powdered Sn-Ag-Cu solder. The solidus and the liquidus......

Effect of rare earth additives on alumina fiber development in Ti-Al intermetallic matrix composites WANG Fen(王 芬)1, 2, FAN Zhi-kang(范志康)1, LIN Ying(林 营)2 1. School of Materials... 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......
employed a complex heat treatment process, involving the pre-tension, thermo-infiltration of the rare earth element Ce, solution treatment, and artificial aging technology. The results indicate that the infiltration of rare earth element Ce benefits the abatement of anisotropy of Al-Li alloy 2195 sheet, in contrast with that of the normal heat treatment process. The gradient of the Vickers-hardness......
