Dual beam ion irradiation response of low activation thin films of nanocrystalline W-Ti-Based compositionally complex alloys
Abstrak
Recently, compositionally complex alloys (CCAs) have been proposed as material candidates for extreme environments, such as for fission or fusion. To explore low activation designed W-Ti-based CCA systems, two new nanocrystalline CCA thin films were synthesized. Single-phase BCC ternary W–Ti–V and quaternary W–Ti–Cr–V CCAs were subjected to in-situ heating and dual-beam ion irradiation investigations at 900 °C. After exposure to 900 °C with and without ion irradiation both systems exhibited negligible grain growth. Small (≤ 1 nm) cavities distributed throughout the film were observed with no radiation induced loop formation post dual-beam ion irradiation up to ∼ 13 dpa. These responses are in excellent agreement with atomistic modeling. Compared to other candidate material systems, these systems possess impressive thermal stabilities and irradiation resistances, while serving as low activation alternatives to W–Ta–based compositionally complex alloys for extreme environments.
