The market for aluminium rolled products

Abstract

Hot-workability tests have been conducted on an Fe-25Cr alloy which dynamically recovers during deformation. Four different oxide-inclusion distributions were introduced into the alloys, and initial grain sizes ranged from coarse cast structures to a fine wrought grain size. The material ductility was shown to decrease dramatically in the presence of air in the furnace atmosphere. For a constant volume fraction of oxide inclusions, the ductility in air, and in argon below 1000°C, decreases with an increase in both inclusion size and initial grain size.
