The article illustrates the influence of ball milling of the 316L and 434L stainless steel powders (medium size of grains was about 135um ) as well as their mixes (75 wt. % of 434L + 25 wt. % of 316L; 50 wt. % of 434L +50 wt. % of 316L and 25 wt. % 434L + 75 wt. % 316L) on their structure.Medium size of the grains(about 20 nm) were obtained after 110 hours of milling. The powders that obtained were pressed isostatically and sintered under hydrogen atmosphere. The samples were then characterized using an optical microscope equipped with a computer image analyser as well as in scaning electron microscope (SEM), equipped with EDS for local chemical analysis.
