Titanium alloy will usher in broad prospects in aviation industry
Sponsored by the China Federation of enterprises and the China Entrepreneur Association, the "2017
China top 500 enterprises Summit Forum" was held on September 9th -10 in Jiangxi, Nanchang province.
Chinese Academy of Sciences Cao Chunxiao attended and delivered a speech. Cao Chunxiao was
working at the China Hangfa Beijing sky Materials Research Institute, today's topic is "and" the aero engine indissoluble bound titanium.
In January last year, the State Council formally approved the establishment of China aviation engine
group, which was formally established in August. The National Aviation Science and technology major of
aero-engine and gas turbine has also been officially launched this year. The aviation engine is the
crystallization of high technology. It is very difficult. It is also the concentrated expression of the
comprehensive national strength of our country and an important symbol of an innovative country.
"Generation of material technology, generation aviation equipment", it is the true portraiture of
development history of world aviation." Cao Chunxiao said, and the titanium alloy is an important
member of the large family of aviation materials, and the engine plays an important role in aviation
equipment. Titanium in the last century, the advent of 50s, greatly promoted the development of aero-
engine aero engine needs strong promoted the development of titanium, between the two is the
dialectical relations, interdependence, mutual promotion and the achievements of the marriage
between titanium and aero engine.
Process innovation is a very effective way to promote the development and application of titanium alloys.
With the emergence of composite materials, not only are they used in large quantities on airplanes, but
also the engines are involved. For example, the engines above 787 and 747 use composite materials
instead of titanium alloys. It turned out that the inherent status of titanium alloys may be gradually
replaced by composite materials. But the composite is not to say that all composite materials, Cao
Chunxiao said, because the bird after loaded on the plane to fall apart, so the front or side with titanium,
titanium alloy wrapped, but overall composite materials accounted for a large part of the weight.
"Looking to the future, the titanium alloy will not be accepted by the dark horse and will continue to
expand its sphere of influence." Cao Chunxiao said, titanium aluminum alloy will usher in a very broad
prospects. U. S. NASA predicts that the use of titanium aluminum compounds in aviation could reach
20% by 2020. However, great progress has been made in the study of titanium aluminum metal bond
compounds in China. The titanium alloy low pressure turbine blade precision castings have been
developed by the Institute of metal science of the Chinese
