Popis: The influence of solidification microstructure on σ-phase precipitation in two refractory stainless steels (26Cr–3Ni) with different microstructures is analyzed. Depending upon cooling rates the existence of Cr 7 C 3 strongly increases the σ-phase precipitation rate, whereas σ precipitation is delayed when this carbide is not present in the alloy.
