Abstract:This project centered on a close interaction between the TCON Division of
Fireline, Inc. and various individuals affiliated with the College of Science, Technology,
Engineering, and Mathematics (STEM) at Youngstown State University (YSU). Fireline,
a local company within 10 minutes walking distance from the YSU campus core, has
developed a unique process that utilizes displacement reactions to transform ceramic
preforms into ceramic-metallic co-continuous interpenetrating phase composites with
enhanced properties while retaining the original shape and dimensions of the preform.
Through initial development efforts, it was discovered that TCON
composite materials
have extraordinary macro-, micro-, and nanoscale features that lead to their exceptional
properties ideal for applications that require cost effective, lightweight materials. The
unique properties of TCON composites in general are derived from the fine interlocking
of ceramic and metallic phases throughout the composite microstructure. The ceramic
phase provides high stiffness, low density and high strength to the composite, while the
continuous network of reinforced metal gives high thermal & electrical conductivity, and
high fracture toughness to the material. Such properties make these materials excellent
candidates for replacing traditional materials in a number of applications, such as high
wear/corrosion resistant refractory shapes for molten metal transport and/or
containment in industrial processes (the major area in which Fireline currently
commercializes some of its TCON products), or for new applications, including light
weight, high strength components for vehicle braking systems.
