Predicting slag viscosities in metallurgical systems 总被引:1,自引:0,他引:1

Slag viscosity is a major process variable for most pyrometallurgical smelting and refining process operations. While extensive
measurements have been made of slag viscosities, it is not practicable to provide data on all the possible combinations of
compositions and process conditions encountered in metallurgical practice. This article reviews the mathematical models that
have been developed to predict slag viscosities and provides some advice on the factors to be considered in their selection
and use. 相似文献

Electromigration is a serious potential source of failure in the narrow, thin-film Al-Cu conductors used in modern microelectronic devices. The problem has become more acute as line widths have shrunk to below one micrometer, creating lines with quasi-bamboo microstructures. The usual mechanism of internal electromigration failure in such lines involves the formation of a transgranular void across a bamboo grain at the upstream end of a long, polygranular segment, preceded by the depletion of copper from both the polygranular segment and the upstream bamboo grain. At least three metallurgical mechanisms are available to inhibit this failure mechanism and improve the useful lifetime of the line, Each of these methods has been demonstrated in the laboratory environment. 相似文献
