ABSTRACT:
A method of forming thin metal sections of reactive metals which prevents high-temperature accelerated corrosion during hot working. The reactive metal section is placed in a non-reactive metal frame. Two non-reactive metal sections are machined to form depressions in which a release agent is deposited. The framed reactive metal section is interleaved between the two non-reactive metal sections such that the release agent is interposed between the principal surfaces of the reactive metal section and the non-reactive metal sections. The assembly is then clampled and welded together along the perimeter. The laminate structure is hot worked as by hot rolling to the desired gauge. The release agent flows to form a continuous barrier during hot working which prevents bonding of the non-reactive sections to the reactive metal section. Since the reactive metal section is encapsulated in a non-reactive metal jacket, oxidation and other degradation of the reactive metal section during hot working is prevented. When the formed assembly is cooled after hot working, the edges of the assembly are sheared off, and the protective metal jacket is stripped from the formed reactive metal section by virtue of the release agent.
