The shape memory effect in systems Cu-based alloysBezjak, Jožica (Avtor) shape memory alloysmartensite trnsformation330a The aim of this work was to analyse the mechanisms of hindered internal passivation of silver based alloys which was obtained by the modification of basic chemical composition. A generalisation of the phenomenon, experimental verification and the estimated range of micro-element concentration is also introduced. The ability for inoculation of a particular alloy is determined by the differences between the formation energies of oxides, as well as their crystallographic similarity. Therefore, for the investigated Ag-Zn alloys, Mg was selected as the micro-alloying element. The influence of 0.001 up to 0.5 mass % of Mg added to the selected alloys was analysed. By changing the chemical composition,internal passivation was hindered, internal oxidation rate was increased, and considerably greater (redoubled) depths of internal oxidation were achieved.20132013-10-15 12:08:35Delo ni kategorizirano3409sl
