AI总结:

本研究探讨高压扭转纳米结构化对Eurofer-97辐照硬化的影响,发现严重变形材料在辐照下硬化减少,尤其在应变60-160范围,为降低辐照硬化提供新途径。

摘要:

我们研究了通过高压扭转(HPT)实现纳米结构化对Eurofer-97辐照性能的影响。材料被变形至剪切应变从0到约230,随后暴露于Fe$^{3+}$辐照剂量为0.01和0.1位移每原子(dpa)的条件下。纳米压痕硬度随变形单调增加,且对于未变形材料,随辐照增加。对于两种损伤水平,在严重变形材料中观察到较少的辐照硬化。此效应在应变范围约60至约160时最为显著,表明纳米结构化可能为减少辐照硬化提供一种方法。

英文摘要:

We investigated the effect of nano-structuring by high-pressure torsion (HPT) on the irradiation performance of Eurofer-97. Material was deformed to shear strains from 0 to ~230, and then exposed to Fe$^{3+}$ irradiation doses of 0.01 and 0.1 displacements-per-atom (dpa). Nanoindentation hardness increases monotonically with deformation, and with irradiation for the undeformed material. For both damage levels, less irradiation hardening is observed in severely deformed material. This effect is most prominent in the strain range ~60 to ~160, suggesting that nano-structuring may provide an approach for reducing irradiation hardening.
