In questo lavoro è stato studiato l'effetto di modeste differenze nel contenuto di carbonio e di azoto sulla deformazione e il comportamento a frattura a temperatura ambiente di un acciaio inossidabile austenitico AISI 304. Nell'acciaio contenente il più basso contenuto degli elementi interstiziali si forma una maggiore quantità di martensite indotta dalla deformazione plastica dell'austenite; ne risulta un aumento dell'incrudimento, della deformazione uniforme e della deformazione totale. La presenza di aree martensitiche di dimensioni significative nella sezione resistente causa però localizzazione della deformazione all'interfaccia austenite/martensite, e questo promuove la nucleazione di cricche e la loro propagazione all'interfaccia stesso. Questo fenomeno determina una diminuzione di UTS. La trasformazione martensitica indotta dalla deformazione causa inoltre una diminuzione della "strain rate sensitivity".
