High Heat Flux Tests of Tungsten – RAFM Steel Mock-up Brazed by Ti-Zr-4Be Alloy / D.M.Bachurina, T.N.Vershinina, [a.o.] // Fusion Engineering and Design [Electronic resource]. – 2025. – Vol. 211. – P. 114790. – URL: https://doi.org/10.1016/j.fusengdes.2024.114790. – Bibliogr.: 21.

This work focuses on the development of Plasma Facing Components (PFC) for future fusion reactors. One of the main challenges is to provide a firm joint between Plasma Facing Materials (PFM), such as tungsten (W), and structural material, such as Reduced-Activation Ferritic-Martensitic (RAFM) steel. This work advances the development of the W/48Ti-48Zr-4Be/Ta/48Ti-48Zr-4Be/Rusfer joint, where 48Ti-48Zr-4Be wt.% is a brazing alloy and Ta is an interlayer that mitigates the mismatch in the CTE between W and the Rusfer steel. We investigated the high heat flux performance (HHFT) of this joint, which included the design of a water-cooled PFC, its fabrication and HHFT at the IDTF stand. A thermal cycling test with a stepwise increase in heat flux from 2.5 MW/m&sup(2) to 4.5 MW/m&sup(2) was conducted. The breakdown of the mock-up took place after 1055 cycles at the Ta/RAFM surface. The fracture surface was investigated using SEM and XRD, which revealed fatigue failure along the (Zr,Ti)&sub(2)(Fe,Cr,Ta) and Ta&sub(2)Be phases.
