| 英文摘要 | The present work developed a new Fe-based superalloy of Fe-10.9Cr-13.9Ni-6.4Al-2.2Mo-0.5W-0.04Zr-0.005B (weight percent, wt. %) with cuboidal B2 nanoparticles coherently precipitated into the body-centred-cubic (BCC) matrix. This alloy possesses excellent microstructural stability at 973 K with a slow particle coarsening rate and the B2 nanoprecipitates still keep cuboidal after 1000 h-aging, which is ascribed to the moderate lattice misfit (epsilon = 0.24-0.67%) between BCC and B2 phases. Also, the current alloy exhibits a prominent mechanical property with a high yield strength of sigma(YS) = 238-258 MPa at 973 K. IMPACT STATEMENT A Fe-based superalloy with cuboidal B2 nanoparticles coherently precipitated into BCC matrix exhibits high microstructural stability and prominent mechanical property at 973 K. |
