The structural changes of Ag-Sn films on carbon film have been observed during heating to about 640℃ by using TEM and HVEM. Raising the temperature to 200-250℃, silver and tin react rapidly to form γ phase Ag8Sn. Raising the temperature above 480℃, the γ phase transforms suddenly into laminar β phase. At about 510℃, the β phase film begins to agglomerate. The morphology of the Ag-Sn films on GaAs substrate after heating has been observed by using SEM.

Raising the temperature to 200-250℃, silver and tin react rapidly to form γ phase Ag8Sn. Raising the temperature above 480℃, the γ phase transforms suddenly into laminar β phase. At about 510℃, the β phase film begins to agglomerate. The morphology of the Ag-Sn films on GaAs substrate after heating has been observed by using SEM. It is shown that when the tin content of Ag-Sn films (20-65wt%Sn) is greater and the alloying temperature is higher, the agglomeration of the film is more severe.

借助TEM和HVEM观察了碳膜上Ag-Sn薄膜在加热到640℃的过程中的结构变化。升温到200—250℃时,Ag和Sn迅速反应变为γ相Ag_3Sn。γ相在480℃以上迅速转变成具有片层状组织的β相。在510℃左右,β相薄膜开始产生缩聚。还用扫描电子显微镜观察了GaAs基底上Ag-sn膜加热后的表面形态。结果表明,若Sn含量(20—65Wt%)越多、合金温度越高,则合金膜表层缩聚越严重。

We have in this paper collected 94 experimental data home and overseas of Nb3Sn multifilamentary superconductors prepared by bronze technique. Using these data, a step-by-step regression analysis on the relation between the Nb3Sn layer thickness and six process parameters have been made by using a TQ-16 digit computer. An optimum regression mathematical model for calculating the Nb3Sn layer thickness is given as follows:Where,Y-The Nb3Sn layer thickness (μm),x1-The period of heat treatment (hr./100),X2-The temperature of heat treatment (℃/100),x3-The tin content in bronze matrix before heat treatment (Wt.% ×100),x4-The volume ratio of bronze to Nb,x5-The diameter of the Nb filament (mm),x6-n/100, where n is number of filaments.The complex correlation coefficient R and the standard error of estimate for this model are 0.969 and 0.263 respectively. The .F-value of this model is as high as 110 (F0.1=2.4). Therefore, the model is so significant that it may be used to predict or control the Nb3Sn layer thickness. Based on this model, the ranges of time and temperature in optimum heat treatment for Nb3Sn formation have been also discussed.
