No. 892: New titanium material that is three times as strong as existing titanium material (August 29, 2017)

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.
