Abstract
A method of forming a composite sheet includes the steps of: providing a first sheet having a surface and including a metal or alloy, the first sheet having a given strength characteristic; providing a second sheet having a surface and a strength characteristic that is superior to the given strength characteristic of the first sheet; disposing the first sheet and the second sheet in an aligned opposing position with at least a portion of the surface of the first sheet touching the surface of the first sheet to form a contact area; and bonding the first sheet to the second sheet at least in part by applying an oscillating ultrasonic force to at least one of the first sheet and the second sheet to form a composite sheet, the first sheet having a cube texture characterized by a φ-scan having a FWHM of no more than 15° in all directions.
