The results presented in this paper show that paarticles grow by bulk diffusion controlled with the diffusivity of selenium and tellurium in silver. It was also found that particle radius follows ?$R^2$?-t relationship at all temperatures of the experimentZ raziskavami visokotemperaturne nestabilnosti mikrostrukture zlitin Ag - 1,2 at.% Se in Ag - 1,2 at.% Te smo določili kinetiko in aktivacijsko energijo rasti delcev intermetalne faze. V prispevku predstavljeni rezultati kažejo, da je rast delcev kontrolirana z volumsko difuzijo selena in telurja v srebru in da kvadrat polmera delcev s časom narašča linearno (?$R^2$?-t) pri vseh raziskanih tempeaturahTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
