Integrated manufacturing method of high-temperature-resistant thin-wall component by laying metal foil strips for blank making

Abstract

The invention discloses an integrated manufacturing method for a high-temperature-resistant thin-wall component by laying metal foil strips for blank making. The method comprises the steps of designing a prefabricated blank; preparing a supporting mold; determining the thickness of the foil strips; determining the width of the foil strips; formulating a laying process; laying the foil strips A andthe foil strips B; preparing the AB laminated prefabricated blank; performing bulging forming on the prefabricated blank; performing reaction synthesis and densification treatment on the bulged component; performing subsequent treatment on the thin-walled component and the like. According to the method, the thin-wall integrally-prefabricated blank which is complex in structure, uniform in wall thickness and similar to a final part in shape can be obtained by continuously laying the metal foil strips with proper widths, the thin-wall prefabricated blank does not need to be welded, the problemthat the comprehensive performance of a welding area is weak when a laminated plate blank is firstly prepared and then roll-welded into a cylinder blank at present is solved, meanwhile, the deformation during subsequent bulging is reduced, and the defects of local bulging, thinning and cracking, undercut at the parting position in the mold closing process or wrinkling caused by uneven distributionof materials in all areas are avoided.

Description

technical field [0001] The invention relates to the technical field of manufacturing thin-walled components, in particular to an integrated manufacturing method for high-temperature-resistant thin-walled components by laying metal foil strips to make blanks. Background technique [0002] With the rapid development of aviation and aerospace technology, the flight distance and flight speed of the new generation of aircraft continue to increase, and the service temperature of complex thin-walled components such as air inlets, exhaust nozzles and other high-temperature structures in the aircraft is also increasing. The heat-resistant temperature (about 500°C) of existing titanium alloys and high-temperature alloys can no longer meet the requirements. At this time, it is necessary to use materials with higher heat resistance temperature such as intermetallic compounds such as TiAl and NiAl. The service temperature of TiAl is 600-850°C, and the service temperature of NiAl is as h...
