Sažetak

Analiziran je uticaj mikrostrukture na razvoj plastične deformacije u okolini propagirajuće prsline u leguri Mg kod koje je otpornost na koroziju povećana dodatkom 0.5 wt. % Ca. Prslina je inicirana savijanjem u 3 tačke sa postepenim dodavanjem opterećenja. Rezultati ove analize ukazuju na značajnije prisustvo traga klizanja i deformacije dvojnikovanjem posle potpune poliedrizacije zrna u poređenju sa materijalom u stanju livenja.
