[0002] Bimetal is a layered metal composite material composed of two or more metals with different properties forming a metallurgical bond at the interface. Through composite technology, the advantages of different metals are combined together to overcome the shortcomings of a single material and achieve complementary performance.

[0003] The materials are stacked in the order of cemented carbide, iron foil, vanadium foil and titanium alloy to form a blank to be composited. Finally, the blank is placed in a hot pressing furnace and hot pressed and diffused composited at 850℃-950℃ and 10-20MPa pressure for 40-60min under vacuum or inert atmosphere. After cooling in the furnace, a bimetallic layered composite material can be obtained.
