| 英文摘要 | The study investigates the impact of thermal aging at 650 degrees C on the microstructure and precipitated phase of China Low-activation Ferrite (CLF-1) steel, which has undergone titanium strengthening and thermo-mechanical treatment (TMT). High-resolution experiments were conducted to explore changes in the size, degree of coherence, and interfacial free energy of the MC phase after a 2000-hour aging duration. Additionally, Density Functional Theory (DFT) calculations were employed to examine the stability differences between (Ta/V)C and TiC phases under various crystal planes. The experimental results indicated that the TiC phase exhibited three distinct manifestations: coherent but with a large size, non-coherent but with a small size, and non-coherent with a large size. Notably, higher interface free energy corresponded to lower particle stability. Through an investigation of the change in binding energy and surface energy across various crystal planes, it was discovered that certain TiC phases undergo growth and coarsening specifically under the (220) crystal planes due to variations in energy density after long-term aging. This study provides novel insights into the stability of precipitate phases, offering valuable implications for materials design. |
