Laminated Ferrous Composites Based on Ultrahigh Carbon (UHC) Steels.

Abstract

Ferrous laminated composites based on ultrahigh carbon (UHC) steel have been successfully manufactured by roll bonding below the Al transition temperature. Three unique mechanical property characteristics have been achieved by such lamination. First, remarkably high notch-impact propertiesare achieved in such laminates. This is because notch-blunting occurs by delamination at the good (but not perfect) bond at the interface between laminates. Second, the fatigue properties of UHC steel are improved by lamination for the same reason. The requirements for delamination, however, are much more stringent for fatigue enhancement than for notch-impact enhancement. Third, non-superplastic materials, such as stainless steel, are made superplastic by lamination with fine-grained UHC steel. A ferritic stainless steel was shown to exhibit over 1000% elongation at 800 C when tested as a 15% stainless steel / UHC steel laminated composite.
