Titanium alloy is a kind of important structural metallic materials developed in the 1950’s, has excellent comprehensive performance. The material has characteristics like small density, light weight, heat resistance, corrosion resistance, flexibility, good elasticity and forming process etc.
Aerospace industry is the biggest consumer of titanium, titanium alloy production has very close relationship with the aerospace investment. Nearly in ten years in the 1990’s, an application for a patent falling back. Since 2000, the titanium alloy related patent quantity appeared obvious growth trend. “On one side, this shows that titanium alloy has potential research space, on the other hand, is has great relationship with our country in recent years, strengthen the related research in the field of titanium alloy.” Document information center of Chinese academy of sciences researchers Chen said.
Most analysis data shows that the technology of titanium alloy is held in Japan (41%), China (22%), the United States (14%) and Russia (8%) of the four countries, the subtotal takes 85% of the global patent.
