摘要:

采用室温拉伸、500℃高温拉伸、显微硬度、SEM、TEM等方法研究中国低活化马氏体钢(CLAM钢)多道次模压变形诱导沉淀相回溶和析出对力学性能的影响。结果表明，三道次模压变形后，有效细化了晶粒和沉淀相，尺寸为5 μm以上的晶粒所占体积分数减小为0.49%，M₂₃C₆相和MX相平均尺寸分别从107.32和17.12 nm减小到93.97和13.59 nm。累积应变为2.32时，抗拉强度和硬度分别为720 MPa和2.46 GPa，较变形前分别增加了22.87%和12.33%；当累积应变达到3.48时，与累积应变为2.32时相比其强度降低了4.31%，硬度和延伸率分别上升了2.03%和6.27%，该变化与变形过程中发生明显的沉淀相回溶有关。

Abstract：

In this work, a constrained groove pressing experiment was carried out to investigate the influence of constrained groove pressing on precipitated phase dissolution and mechanical properties of China low activation martensitic (CLAM) steels. The aim of this study is to improve the comprehensive service performances of CLAM steels used in the first wall of fusion reactor cladding. The influence of the dissolution and precipitation of precipitates on the mechanical properties of CLAM steel subjected to multi-pass groove pressing was investigated via tensile tests at room temperature and 500^oC, microhardness tests, SEM, and TEM. The results show that the grains and precipitated phases are effectively refined after three passes of groove pressing, the volume fraction of grains above 5 μm is reduced to 0.49%, and the average size of M₂₃C₆ and MX phases is reduced from 107.32 and 17.12 nm to 93.97 and 13.59 nm, respectively. When the cumulative strain of the billets reaches a value of 2.32 (pass two), the tensile strength and microhardness are found to be 720 MPa and 2.46 GPa, respectively. When the cumulative strain increases to 3.48 (pass three), the strength of the CLAM steel decreases by 4.31%, whereas the microhardness and elongation increase by 2.03% and 6.27%, respectively. These trends are related to the evident dissolution of the precipitates during the deformation process.

Key words： China low activation martensitic steel constrained groove pressing precipitation strengthening mechanical property
