Abstract

An apparatus and process are described which are used in the production of a ballistic product such as an armor plate, which begins with titanium preform in the form of a thick sheet and which is submerged in a molten A1 bath. By submerging Ti preform in a volume of molten A1, a layer of intermetallic compound titanium aluminide (TiA13) is formed into the Ti preform, resulting in a dimensional (primarily thickness) increase; this dimensional (thickness) increase is due to a slightly lower density of the Titanium aluminide (TiA13) compared to that of the titanium metal. It is therefore required to choose starting dimensions (primarily thickness) of the titanium preform to accommodate the dimensional changes so as to achieve a final net shape (primarily thickness) for the ballistic product.
