The invention discloses a synthesis, preparation and forming integrated method of a NiAl alloy hook face plate component, relates to a synthesis, preparation and forming integrated method of an intermetallic compound hook face plate component, and aims to solve the technical problem that thermoforming of the hook face plate component is difficult because the existing NiAl alloy plate blank is poor in plasticity. The synthesis, preparation and forming integrated method comprises the following main steps: I, laminating and hot pressing Ni foils and Al foils alternately to obtain a Ni / Al lamination composite board; II, carrying out hot gas bulging forming on the Ni / Al lamination composite board to obtain the demanded shape and size, and enabling the Ni foils and the Al foils to react in a hot gas bulging forming die to synthesize a Ni-Al intermetallic compound; III, taking a forming piece out of the hot gas bulging forming die and putting the forming piece in a vacuum thermal treatment furnace for high-temperature vacuum thermal treatment to enable the generated Ni-Al intermetallic compound to completely react so as to generate NiAl alloy; and IV, putting the forming piece after thermal treatment in the hot gas bulging forming die, and carrying out densification treatment under the high-pressure gas bulging action. The synthesis, preparation and forming integrated method is suitable for preparation and forming of the NiAl alloy hook face plate component.
