Abstract: A damping panel includes a first metal and a second metal. The first metal has a first surface and a second surface opposite the first surface. The second metal portion has a third surface and a fourth surface opposite the third surface. A fixed region is where the second surface of the first metal is fixed to the third surface of the second metal. A non-fixed region is where the second surface is not fixed to the third surface. A cavity is disposed between the second surface and the third surface at the non-fixed region. A damping material is disposed on at least one of: at least a portion of the cavity on the second surface, at least a portion of the cavity on the third surface, at least a portion of the first surface, and at least a portion of the fourth surface.

Abstract: The present disclosure provides a method of preparing a metal sheet. The method includes extruding a component along an extrusion axis. The component has a wall at least partially defining an interior region. The component includes a metal. The method further includes unfurling the wall to form a sheet precursor. The sheet precursor has a first thickness and a first transverse dimension. The method further includes rolling the sheet precursor along a rolling axis to form the metal sheet. The metal sheet has a second thickness perpendicular to the rolling axis. The second thickness is less than the first thickness. The second transverse dimension is parallel to the rolling axis. The second transverse dimension is greater than the first transverse dimension. In certain aspects, the metal includes lithium and the metal sheet is a lithium metal electrode.

Abstract: An alloy composition is provided. The alloy composition includes silicon (Si) at a concentration of greater than or equal to about 0.55 wt. % to less than or equal to about 0.75 wt. %, magnesium (Mg) at a concentration of greater than or equal to about 0.55 wt. % to less than or equal to about 0.75 wt. %, chromium (Cr) at a concentration of greater than or equal to about 0.15 wt. % to less than or equal to about 0.3 wt. %, and a balance of the alloy composition being aluminum (Al). The alloy composition has an intermetallic phase content of less than or equal to about 3 wt. %. Methods of preparing the alloy composition and of processing the alloy composition are also provided.
