Abstract: Intermetallic compounds(IMC) formed at Sn-Ag-Cu solder droplet/pad interface during wetting reaction were investigated. Comparative studies of the IMC evolution during reflow... during wetting reaction. After reflow, all Au layer disappears from the interface, Au element is dissolved into solder and Au-Sn intermetallic compounds are precipitated in the bulk. Reaction between......

According to BIRBILIS and BUCHHEIT [11], cathodic efficiency of Fe-rich... of copper-rich intermetallic particles [5-7]. Local microgalvanic coupling is established between the inhomogeneities and aluminium matrix and essentially causes localized attack [8-13]. Coarse......
Sb掺杂对Mg2Si基化合物热电性能的影响 张倩1,殷浩1,朱铁军1,赵新兵1 (1.浙江大学,硅材料国家重点实验室,浙江,杭州,310027) 摘要:采用感应熔炼和真空热压的方法制备了Sb掺杂和未掺杂的Mg2Si基热电材料.研究了Sb掺杂对Mg2Si基热电材料的结构以及热电特性的影响.结果表明:通过Sb掺杂使得载流子浓度从3.07x1019 cm-3增加到1.25x1020 cm-3,电子有效质量也相应增加.测试了从室温到800 K下试样的Seebeck系数,电导率和热导率.结果显示,0.3 at%Sb掺杂使得电导率得到显著增加,在783 K时,ZT值达到0.7. 关键词:热电; 金属间化合物; 掺杂; thermoelectric; intermetallic alloys and compounds; doping; [全文内容正在添加中] ......
