用于先进核能系统的12Cr-- ODS 铁素体钢的显微组织和力学性能
Microstructure and mechanical properties of 12Cr-ODS ferritic steel for advanced nuclear energy systems
摘要
Abstract
Taking 12Cr-0. 5Ti-1W gas atomized powders and nona-Y2 O3 as pre-alloyed powders, 12Cr oxide dispersion strength-ened (ODS) ferritic steel was fabricated by mechanical alloying (MA) and hot isostatic pressing (HIP). The properties of the ferritic steel were improved by forging and heat treatment. Nano-oxide particles were observed in the microstructure by transmission electron microscopy, and these precipitated particles were identified to be Y-Ti-O complex compounds by energy dispersive X-ray spectroscopy. The mechanical properties of the ferritic steel were analyzed by tensile strength test and ultrasonic non-destructive test.关键词
