METHOD OF JOINING OF PURE TI/TI-BASE ALLOY AND FE-BASE STEEL ALLOY USING AG-BASED INSERTED MATERIAL AND AG DIFFUSION CONTROL LAYER

摘要

PURPOSE: A method of joining of pure Ti/Ti-base alloy and Fe-base steel alloy using Ag-based inserted material and an Ag diffusion control layer are provided to improve the toughness of a junction and to have brittle protecting by suppressing intermetallic compound. CONSTITUTION: A silver diffusion control layer(B) is formed in titanium or Ti alloy base material. An silver system interposer which does not contain the titanium component are placed between steel series alloy(A2) and the titanium or titanium alloy base material, in which the silver diffusion control layer. The silver system interposer is heated at a melting point of the interposer and the titanium or titanium alloy base material and the steel series alloy are connected.
