RECENT PROGRESS IN THE FABRICATION AND CHARACTERIZATION OF DUCTILE-PHASE-TOUGHENED TUNGSTEN COMPOSITES FOR PLASMA-FACING MATERIALS
A promising approach to increasing fracture toughness and decreasing the DBTT of a W-alloy is by ductile-phase toughening (DPT). In this method, a ductile phase is included in a brittle matrix to prevent crack propagation by bridging. Composite specimens were fabricated by two methods: 1) sintering W powders together with carburized W wires, and 2) hot pressing W and Cu foils together with W wires. These composites were tested in tension and three-point bending.
