Abstract

The invention discloses an aluminium alloy and an aluminium alloy composite liquid phase connected die forging integral forming method of a material, and relates to a material forming method. The technical problems of difficulty in connection and low intensity in the conventional material connection method are solved. The method comprises the following steps of: removing oil stains and impurities on the surface to be connected of the material to be connected; 2, respecting heating the materials to be connected which processed in the first step to a plastic deformation temperature under the protection of vacuum or inert gas, and keeping the temperature until the temperature of all parts of the materials are consistent; and continuously heating to ensure that the temperature of the material to be connected is quickly raised to a melting point temperature and is kept to melt the surface layer of the material; and 3, placing the material to be connected which is treated in the second step into a die cavity of a hot press for hot-pressing formation, or placing the material to be connected between rollers of a rolling machine for performing rolling formation so as to finish the liquid phase connected die forging integral formation of the material. A joint prepared by the method can be applied to the fields of aerospaces, space technology, nuclear industry, micro-electrons, automobiles and petrochemical industry.
