(under subclass 91) Process of forming a composite article by sequentially casting molten metal.
(1) Note. The sequentially cast molten metal(s) may be cast onto and in contact with the previously cast metal or may be separated from one another by some preformed portion, part or component of the composite article.
(2) Note. The metals cast may be of the same or different materials; however, if the metals cast are the same material, the prior cast metal must be cooled and solidified, i.e., act as a preform, before the subsequent metal is cast.
