The invention relates to an armored vehicle aluminium alloy parts and a method for fast casting a blank battlefield emergency self-propagating. The invention comprises the following technology steps: damaged parts are recovered to prototype by manners of splicing, and the like, which serves as holotype mould. According to sequence of first adding acid and later adding resin, furan resin and catalyst are prepared according to the proportion; the mixture is fast and well blended with silicon sand, and prepared to a mother plate by moulding. The thermit reaction agent is placed in a crucible; TiC inflaming welding fluid is embedded into the thermit reaction agent; part are exposed; the exposed part is lighted; the self-propagating reaction of the thermit reaction agent in the crucible is triggered; when the reaction is finished, solid aluminum alloy is put on the surface of the resultant of reaction to lead the melting of the aluminum to obtain the aluminum alloy liquid; the aluminum alloy liquid is directly cas
