The aging process has been studied by 0.09, 0.28 and 0.48 wt% iron added gold-10 wt% platinum alloys. The results obtained are as follows: (1) From the isochronal and isothermal aging, the electrical resistances decreased in proportion to increasing of iron. These decreases are occured to be ordered of iron and platinum. (2) The electrical resistances in the isochronal aging curves are minimized at limited temperature of 600 degrees approximately 680 degrees C, and the growth of nodules would be saturated at this temperature. (3) The apparent activation energies of aging process of Au-Pt-Fe alloys (0.09, 0.28 and 0.48 wt% Fe) were in the range of about 37 approximately 44 Kcal/mole. (4) In the results of the images atructure of nodules was lamella of fcc FePt3 phase and Au-Pt solid solution phase.
通过添加0.09%、0.28%和0.48%重量比铁的金-10%重量比铂合金研究了老化过程。得到的结果如下：(1) 从等时老化和等温老化来看，电阻随着铁含量的增加而成比例降低。这些降低按铁和铂的顺序发生。(2) 等时老化曲线中的电阻在约600℃至680℃的有限温度下最小化，并且在该温度下结核的生长将达到饱和。(3) Au-Pt-Fe合金（0.09%、0.28%和0.48%重量比铁）老化过程的表观活化能在约37至44千卡/摩尔范围内。(4) 在结核的图像结构结果中，是面心立方FePt3相和Au-Pt固溶体相的薄片。
