The collapse of the Soviet Union has left many of its scientific institutes and technical
universities without their traditional backbone of financial support. In an effort to stem the
export of science to nations advocating nuclear proliferation, and to acquire potentially useful
technology, several U.S. government-sponsored programs have arisen to mine the best of
former USSR scientific advances. In the field of metallurgy, the earliest institutes to be
investigated by Sandia National Laboratories are located in Ukraine. In particular, scientists at
the State Metallurgical Academy have developed unique porous metals, resembling what could
be described as gas-solid "eutectic". While porous metals are available in the U.S. and other
western countries, none have the remarkable structure and properties of these materials. Sandia
began a collaborative program with the Ukrainian scientists to bring this technology to the U.S.,
verify the claims regarding these materials, and begin production of the so-called Gasars. This
paper will describe the casting process technology and metallurgy associated with the
production of Gasars, and will review the progress of the collaborative project.
