Abstract:
A method of making a steel article having a "Damascus" surface pattern wherein a steel melt comprising about 1. 0 to about 2. 0 weight % carbon is solidified to form an ingot, the ingot is heated between about 1100. degree. to about 1299. degree. C. for a time at temperature of about 5 to about 12 hours, a malleable envelope is formed about the ingot separately or concurrently with the heat treatment, and the enveloped ingot is shaped (e. g. , forged) initially at an ingot temperature above the A. sub. r-gr temperature but below the liquidus temperature and then at an ingot temperature below the A. sub. cm temperature. The envelope is then removed from the shaped ingot.
