“…As it was shown in [45], ductile materials like Cu and Ni reduce residual stresses more efficiently than materials with a medium CTE (V, Ta). Pure copper as a brazing alloy was first presented in [33], though copper alloys had been widely investigated before.…”

A Demonstration (DEMO) thermonuclear reactor is the next step after the International Thermonuclear Experimental Reactor (ITER). Designs for a DEMO divertor and the First Wall require the joining of tungsten to steel; this is a difficult task, however, because of the metals’ physical properties and necessary operating conditions. Brazing is a prospective technology that could be used to solve this problem. This work examines a state-of-the-art solution to the problem of joining tungsten to steel by brazing, in order to summarize best practices, identify shortcomings, and clarify mechanical property requirements. Here, we outline the ways in which brazing technology can be developed to join tungsten to steel for use in a DEMO application.

“…The low activation metal of vanadium has a CTE of [43], located in between those of RAFMs [47] and W [48], suitable for this interlayer application. When used together with Fe-based amorphous alloys for brazing, the formation of brittle σ-VFe phase at their interface is hardly avoided.…”

The joining of Tungsten (W) and reduced activation ferritic–martensitic steel (RAFMs) is crucial to the fabrication of divertors in future fusion reactors. In this work, an Fe75.0Si8.33B16.67 (at.-%) amorphous filler and iron interlayer are considered for brazing W and RAFMs. Crack-free joints in both the as-brazed and post joining heat treatment (PJHT) states have been obtained by short-time vacuum brazing at 1230°C. The bonding seams of the joints are composed of an α-Fe matrix, fine FeWB and Fe3B particles. The PJHT joint exhibits a high strength of 310 MPa and room temperature plasticity. The strong and tough joint would be appealing in its thermal cycling and thermal shock performance.
