W-EUROFER97 brazed joints using Ag, Au, and Cu-based fillers for energy applications: A microstructural and mechanical study

The brazeability of four different alloys (Au, Cu, and two Ag-based alloys) was evaluated for their use as filler materials in joints between EUROFER 97 and tungsten for its application in future fusion reactors. The study aims to analyze the operational brazeability in terms of deep microstructural...
