Influence of small amount and different morphology of secondary phases on impact toughness of UNS S32205 Duplex Stainless Steel

The wrought material retained a very good impact toughness even at − 90 °C (100 J), but a small volume fraction of secondary phases affected the impact toughness even at room temperature. Coarser secondary phases affect the impact toughness largely as compared to small and finely dispersed particles.
