The object of research is jewelry and jewelry alloys of various functional purposes, which are represented by typical examples of the range of the jewelry market. The purpose of the work is the development of compositions of alloys on the basis of gold, taking into account the composition of their main and alloying components, modifiers by way of directed regulation of structuring and receipt of jewelry with improved indexes of strength, hardness, safety. Methods of research - general scientific methods of optimization, comparative and system analysis, as well as methods of mathematical logic, diagnostic, informational and analytical methods, including mathematical, expert, logical, organoleptic, physical and chemical. The positive effect of the modifying impurities Zn, Zr, Mn, Co, Ga, as well as the combined B-Si impurities on the regulation of the physical-mechanical properties, grains and form-fill properties of gold-based alloys has been experimentally established, as compared to samples of standard alloys that do not contain any additives . The efficiency of application of a composition of alloys on a basis of gold with the maintenance of complexes of modifying impurities, which provides improvement of consumer properties of jewelry products, is proved.
