[Investigations of sag-resistance of precious alloys for porcelain fusing. (Part 2) The effect of Fe, In, Sn addition on the distortion at high temperature of 85% Au alloys for porcelain fusing (author's transl)].

Abstract

Fifteen alloys were prepared by adding 0-1.00 wt% Fe, In and Sn (total amount 1.00 wt%) to 85 Au-10 Pd-5 Pt master alloy. The distortion at high temperature in the firing cycle was measured by the apparatus for trial manufacture reported in the preceding paper, and the influence of each additional elements was discussed. The results were summarized as follows; 1) The distortion of the alloys containing additional elements (Fe, In and/or Sn) was obviously less than that of the master alloy. 2) The distortion of the alloys containing only 1 wt% Fe was the least in all of the alloys. 3) Adding both In and Sn had tendency to less distortion at high temperature, but the adding effect was less than that of Fe.
