Abstract

Methods and process flows for diffusion bonding and forming metallic sheets are disclosed herein. The methods include stacking a first metallic sheet and a second metallic sheet to define a sheet stack. The methods further include creating a pneumatic seal between the first metallic sheet and the second metallic sheet to define a sealed sheet stack that defines a pneumatically isolated region. The methods also include increasing a surface area of the sealed sheet stack to define an expanded sheet stack. The methods further include compressing at least a portion of the expanded sheet stack to form a diffusion bond between a corresponding portion of the first metallic sheet and an opposed portion of the second metallic sheet thereby defining a diffusion bonded sheet stack.
