The Structure of Nanocrystalline Stainless Steel Powders Obtained by Ball Milling and Duplex Stainless Steel Formed by Their Sintering

Abstract:

The article illustrates the influence of ball milling of the 316L and 434L stainless steel powders as well as their mixture (50 wt. % of 434L + 50 wt. % of 316L) on their structure. Medium size of the grains (about 30 nm) was obtained after 110 hours of milling. The powders that obtained were pressed isostatically and sintered by impulse plasma method in vacuum. The samples were then characterized using an optical microscope equipped with a computer image analyzer, scanning electron microscope and X-ray diffractometer.
