英文摘要Two variants of 14-Cr oxide dispersion strengthened FeCrAl alloys are fabricated by MA method. The morphology, phase and oxide/matrix interface structure of the nano-oxide dispersoids in both alloys are characterized by TEM, HRTEM, TKD and XRD. Almost all the small precipitates in Fe-14Cr-4.5Al-2W-0.4Ti-0.4Y alloy are identified as orthorhombic YAlO3 particles. In Fe-14Cr-4.5Al-2W-0.4Ti-0.3Zr-0.4Y ODS alloy, Y-2(Zr0.4Ti0.6)(2)O-7 particle with better coherent relationship with the matrix is found. Almost 23% Y-2(Zr0.4Ti0.6)(2)O-7 and YAlO3 particles coexist, resulting in refinement of average diameter of oxide dispersoids and improvement of mechanical strength. Tensile tests from room temperature to 1000 degrees C demonstrate the attainment of strength-toughness matching in these ODS FeCrAl alloys. The inter-granular fracture after the tensile tests at elevated temperature indicates that grain boundary sliding may be the dominant mechanism for deformation. (C) 2019 Elsevier B.V.
