摘要

2066584 9104347 PCTABS00003 A method is disclosed of making a billet (30) comprising a mass of compressed swarf (34) jacketed in a tubular jacket (32). A number of similar indentations (42) are formed in the ends of the jacket. The indentations are symmetrically disposed about the axis of the billet. The indentations terminate at terminal positions (50) spaced from the ends of the billet and increase in depth from the terminal positions to the ends of the billet. Jackets of various materials are envisaged, in particular of stainless steel and mild steel. Where the jacket is of stainless steel tubular end pieces (32b) of mild steel in which the indentations are formed may be welded thereon.
