Fine Structure and Superplasticity in Ultrahigh Carbon Steels.

Abstract

This program centers on a study of the mechanical behavior of ultrahigh carbon (UHC) steels in the range 1% to 2.4% carbon. These UHC steels were developed at Stanford University during 1973-1976. They were shown to be superplastic at warm temperatures (600 to 800 C) and strong and ductile at room temperature. The objectives of our present study are threefold: (1) to alter the chemistry of the UHC steels in order to optimize superplastic characteristics at elevated temperature and strength and ductility characteristics at room temperature, (2) to investigate various thermal-mechanical processing procedures for obtaining the desired microstructure in the UHC steels and (3) to utilize superplasticity in solid state bonding of similar and dissimilar steels.
