Abstract: A method for processing a raw workpiece into a final workpiece is described, wherein the raw workpiece includes a metallic structure including silicon particles dispersed therein. The raw workpiece is fabricated employing an additive manufacturing process, in one embodiment. The method includes heat-treating the raw workpiece to produce an intermediate workpiece, wherein the heat-treating includes subjecting the raw workpiece to a first temperature environment for a time period to produce an intermediate workpiece to form agglomerated silicon particles, wherein the agglomerated silicon particles are disposed on a surface of the raw workpiece. The method further includes removing the agglomerated silicon particles that are disposed on the surface of the intermediate workpiece.

Abstract: A protective seal cap assembly for enclosing an end portion of a fastener extending through a structure, which includes a cap member. The cap member includes a sidewall which defines an opening and defines an interior space within the sidewall and aligned with the opening, wherein the sidewall defines a central axis. The cap member further includes at least one rib which extends away from an interior surface of the sidewall within the interior space and extends in a direction along the central axis of the cap member.
