Abstract:
    This invention discloses a post-treatment method for steel aluminum-7-graphite solid-liquid composite boards, more specifically, room temperature rolling post-treatment of interfacial shear strength of steel aluminum-7-graphite solid-liquid composite boards. The method performs rolling treatment with a pressing flat down quantity of 2.63% on steel aluminum-7-graphite solid-liquid composite boards, and the shear strength of the boards can be increased to 77.8 MPa, obviously higher than 75 MPa as disclosed in patent CN1710114A.
