Název v původním jazyce

Austenitic stainless steel with yttrium oxide dispersion

Popis výsledku v původním jazyce

Enhancing traditional materials&apos; mechanical properties can be achieved by adding ultrafine oxide particles to inhibit dislocation movement, thus increasing strength. This technique applies to austenitic steels, improving their strength and high-temperature resistance. Understanding oxide dispersion in metal alloys is crucial for developing new high-strength materials. Tin the study we prepared oxide dispersion-strengthened austenitic stainless steel 316L by mechanically alloying of steel powder with Y2O3. Powder precursors were consolidated using Spark Plasma Sintering (SPS) and Pulse Plasma Sintering (PPS) and analyzed for their microstructure. The mechanical properties of the resulting compacts were then evaluated. Initial findings show the formation of chromium-containing carbides due to minor carbon diffusion from graphite tools during SPS or PPS. Y2O3 particles were successfully incorporated into the matrix during mechanical alloying. The mechanical properties varied based on chemical composition and specific conditions of consolidation. Materials with uniformly distributed Y2O3 particles were successfully created using powder metallurgy. Future research will aim to optimize SPS conditions to prevent carbide formation.
