摘要 |
[PROBLEMS] To provide a method for producing an aluminum composite material having a great content of a ceramics with ease. [MEANS FOR SOLVING PROBLEMS] A method which comprises (a) a step of mixing an aluminum powder and ceramic particles, to prepare a mixed material, (b) a step of subjecting the above mixed material to electric pressure sintering together with a metal sheet material, to form a clad material comprising a sintered product covered with the metal sheet material, and (c) a step of subjecting the above clad material to a plastic working to prepare an aluminum composite material. In the (b) step, the mixed material is sandwiched between a pair of metal sheets or a powder of the mixed material is held in a metal container, the mixed material is placed in a molding die in a state in which the metal sheet material is pressurized by a punch, and the mixed material is compressed together with the metal sheet material.
