the steels. The original UHCS [1, 31 were plain carbon steels containing 1 to
2.1%C (this corresponds to 15-32 vol.% iron carbide) with Mn as the only
alloying addition. Subsequently, a number of alloying additions including Cr,
Ni, V, Ti, Mo, Si, P, W, and Al was explored [5, 7, 11]. In either plain carbon or
alloyed form, it was found that the steels could be thermo-mechanically
processed to produce microstructures with fine spheroidized carbides within a
fine-grained ferrite matrix. The processed UHCS possess a unique
combination of properties, not found in other materials, that make them well
suited for structural applications. Specifically, UHCS can have high ambient-
temperature strength, hardness, and ductility, and excellent high-temperature
formability via superplasticity. Included in this UHCS work was a substantial
amount of work carried out on cast irons and iron carbides. A summary is
shown in Table I of the various areas of study within the history of UHCS
development and the specific references for each group are indicated. The six
patents that have been issued on this work are listed and it is noted that
others are planned.
