Abstract:
1. A joining method comprising: joining Fe-based steel and Ti/Ti-based alloys by inserting interlayers and a titanium- or zirconium-based filler alloy between Fe-based steel and Ti/Ti-based alloy base metals; and heating the base metals at a temperature higher than the melting point of the filler alloy and lower than those of the base metals; laminating the interlayers in the order of a nickel layer as a first interlayer, a chrome layer as a second interlayer, and a vanadium, molybdenum or tungsten layer as a third interlayer from the Fe-based steel alloy base metal; and inserting the filler alloy between the vanadium, molybdenum or tungsten layer and the Ti/Ti-based alloy base metal.
