Process for the manufacture of a uniformly bonded composite metal structure

摘要

A process is described for bonding together of metal components wherein the components are explosively bonded together and the resulting composite is treated at elevated temperature. In the process the bond strength over weaker bonded areas is enhanced and the bond strength is rendered more uniform over the total bonded area. The process is especially advantageous for bonding high strength aluminium alloys such as aluminium/lithium alloys, and is particularly useful in the fabrication of composites bonded at selected areas for subsequent expansion to form hollow structures for use in aircraft components.
