of the contact angle is obtained from the solder with 0.1% Nd addition. Key words: lead-free solder; zinc; neodymium; lanthanum; surface tension; wettability CLC number: TN604 Document code...Article ID: 1003-6326(2005)05-1161-05 Effect of Nd and La on surface tension and wettability of Sn-8Zn-3Bi solders ZHOU Jian(周 健), SUN Yang-shan(孙扬善), XUE Feng(薛 烽) (Department......
have a structure which is not completely ordered (from B2 to DO3). Fig.3(c) shows XRD pattern taken from the sample, of which a 175 μm-thick layer is removed from the aluminized surface... is the attribute of the hardness. If the surface of the sample has layered structure, it is not reasonable to test the hardness of sample surface by traditional method. Nano- indentation analysis......
departing from edges, and the thinner sheets (below 10μm) are chiefly breaking from the inner surface. Key words: atomization; close-coupled nozzle; powder; flow structure CLC number: TF123.1 Document... was carried out under the condition of lower melt superheat. The results reveal that there are three approaches about melt metal sheets breakage: from the edges of sheets, from inner surface......
Surface layer structure change and tribological property of Cu/FeS composite under electric fieldMing-Yu Hu,Jie Yu,Xiao-Long Zhou,Zhen-Jun Hong,Wei YeFaculty of Material Science and Engineering... were considered.The results show that some Fe atoms and S atoms break away from the original structure and move along the electric field,but the movement of Fe atoms and S atoms is not synchronized......
J. Cent. South Univ. Technol. (2011) 18: 244-249 DOI: 10.1007/s11771-011-0686-6 Structure realization method for collapse threshold of plastic deformation in train collision condition TIAN Hong... the plastic deformation threshold based on three main aspects of train connection structure, crashworthy vehicle structure, energy-absorbing component. In practical engineering, trains need enough......
kinetics after 10 h. This fact proves the unfavorable effect of the annealing treatment on the original structure on the sample surface. The oxide scale forms on as-coated Ti-48Al-8Cr- 2Ag alloy... changes to faster mass gain kinetics after oxidation for 10 h. This fact proves the unfavorable effect of the annealing treatment on the original structure on the surface of the sample. After being......
