Abstract
O.D.S. ferritic stainless steel has been elaborated by mechanical alloying from elemental powders and fully characterized by SEM, TEM, EDS and XRD.
Macroscopic and microstructural evolutions of the material have been determined as a function of milling time. It has been observed that the changes in composition and structure are dramatic up to 40 milling hours. For higher milling durations, the powder characteristics are nearly unchanged.
Two kinds of reinforcing dispersoids have been identified by TEM on HIP compacted powders : titanium compounds (50-200 nm) in the grain boundaries and complex yttrium oxide nanometer sized particles inside the grains.
