摘要

This study reports the response of helium (He) ion irradiation on binary-phase structured alloy V34 Ti25 Cr10 Ni30 Pd1 . The alloy consists of a VCr matrix with nano-sized TiNi precipitates and a B2 TiNi matrix with nano-sized VCr precipitates. VCr is chemical-disordered and TiNi has a B2-ordered structure. The alloy was subjected to 400 keV He ion irradiation with a fluence of 1 x 1017 ions c m-2 at 450 degrees C. The results show He bubbles within the chemical-disordered VCr matrix exhibit a near-spherical shape with a smaller size and higher density compared to that in chemical-ordered TiNi phase with a larger size, lower density, and faceted shape. This indicates the chemical-disordered VCr phase effectively suppresses He accumulation compared to the B2-ordered TiNi phase, emphasizing the dominance of chemical structures in He bubble formation. The calculation of density functional theory (DFT) shows that Ti and Ni have lower vacancy formation energy than that of V and Cr, respectively, which results in the increased vacancy production in TiNi. Consequently, He bubbles in TiNi have a larger bubble size consistent with experimental observations of radiation-induced Ni segregation. These findings elucidate the roles of ordered and disordered chemical structures in He bubble evolution, offering insights for the development of gas ion irradiation-resistant materials.
