Abstract
Development of materials and related fabrication process is one of the most important technologies for fusion energy development. In fusion reactor, joining of tungsten (W) to reduced activation ferritic/martensitic steel is required. In this work, diffusion bonding between W and ferritic/martensitic steel F82H using a Ti interlayer was investigated. The results indicated that all the joints were successfully obtained. The interfacial microstructure was analyzed by scanning electron microscopy. The chemical composition of these reaction products were determined by energy dispersive spectroscopy. W–Ti solid solution was found at W/Ti interface, while Ti/F82H interface formed complex phases which dependent on the joining temperature. Bond strength was evaluated and the maximum shear strength was obtained for the joint bonded at 900°C. The failure was occurred at Ti/F82H interface during shear testing.
