Abstract: A novel type elasticity-damping composite was manufactured using Cu-Al-Ni-Mn-Ti alloy and QBe₂ alloy by explosion cladding. The damping value of the composite is about 10 times higher than that of the QBe₂ alloy ,and has an obvious amplitude effect . The elect rical resistivity of the composite board is lower than that of the QBe₂alloy but higher than that of the Cu-Al-Ni-Mn-Ti SMA. The boundary of the composite board has a little effect onthe resistivity of the composite board. The shape of the boundary of the composite by explosion cladding is wavelike. At 780 ℃, the boundary of the composite widens with the prolong of the holding time.
