Abstract
The method of making a heterogeneous, Damascus-type cutting blade, comprising forming an open metal enclosure, placing a stack of metal foils in the enclosure, placing a metal plate in the enclosure on top of the stack of foils, folding in portions of the enclosure on said plate to compress the latter and stack of foils, heating and hammering the enclosure and foils to bond the same together, removing the enclosure from the bonded foils, and finish-griding the bonded foils.
Claims21
The method of making a heterogeneous blade-like member constituted of different metals, which includes the steps of working metal to form an open metal enclosure, depositing a stack of different metallic foils in said enclosure through the opening thereof, folding-in portions of said enclosure on said stack of foils to form with said enclosure a tight assemblage, heating said assemblage and applying force to said heated assemblage to attenuate it and bond together the foils of said stack, and thereafter removing said enclosure from the attenuated stack of foils.
The method of making a heterogeneous blade-like member constituted of different metals, which includes the steps of working metal to form an open metal enclosure, depositing a stack of different metallic foils in said enclosure through the opening thereof, placing a metal stripping plate in said enclosure on top of said stack of foils, folding-in portions of said enclosure on said metal plate so as to compress said stack of foils to form with said enclosure a tight assemblage, heating said assemblage and applying force to said heated assemblage to attenuate it and bond together the foils of said stack, and thereafter removing said enclosure and metal plate from the attenuated stack of foils.
