Technology:
Katsuyoshi Kondo, professor at
Osaka University, developed a new titanium material, which is three times as
strong as the existing titanium material jointly with Takefu Special Steel in
Fukui Prefecture and Charmant that is one of Japan’s leading glassframe makers
in Fukui Prefecture. They consolidated oxidized titanium at high temperature
and high pressure, and successfully increased the strength of the existing
titanium material by three times. They plan to translate the new technology
into practical application for medical apparatus and aircraft materials in
three years.
For the development, they adopted
the method of power metallurgy that consolidates power materials. They mixed titanium
and powder of oxidized titanium at 1,000 degrees centigrade and consolidated
them at 60-80 pressure. The new material has tensile strength of 1250 mega,
which is three times as high as that of the existing titanium material. Professor
Kondo told that because the new titanium material is free from rare earths, it
is low-priced and as safe as a kitten. He eyes the possibility of applying it
to parts of aircraft engine and apparatus for brain surgery.
