Integrated manufacturing method of high temperature resistant thin-walled components by laying metal foil strips

Abstract

The invention discloses an integrated manufacturing method of a high-temperature-resistant thin-walled component by laying metal foil strips, including designing a prefabricated blank, preparing a supporting mold, determining the thickness of the foil strip, determining the width of the foil strip, and formulating a laying process Steps such as laying A foil strip and B foil strip, preparing AB laminated prefabricated blank, bulging forming of prefabricated blank, reaction synthesis and densification treatment of components after bulging, and subsequent treatment of thin-walled components; the present invention adopts appropriate The continuous laying of wide metal foil strips can obtain thin-walled integral prefabricated blanks with complex structure, uniform wall thickness, and shape close to the final part. There is no need to weld thin-walled prefabricated blanks, which solves the traditional problem of first preparing laminated slabs and then rolling welding There is a problem of weak comprehensive performance in the welding area when the billet is formed, and at the same time reduce the amount of deformation during the subsequent bulging, avoiding local bulging thinning and cracking, or undercutting at the parting part during the mold closing process, or uneven distribution of materials in each area Wrinkle defects appear.

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...
