Titanium is a new structural material

Titanium is a new structural material, it has excellent performance, such as low density (4.5gcm-3), high specific strength and fracture toughness, fatigue strength and resistance to crack growth, good low-temperature toughness, corrosion resistance excellent, the maximum operating temperature of some titanium alloys for 550 / C, is expected to reach 700 / C. So it gets increasingly widely used in aviation, aerospace, chemical, shipbuilding and other industrial sectors, is developing rapidly. Light alloy, steel, etc. (σ0.2 / density) versus temperature, stronger than the titanium alloy is higher than other light metals, steel and nickel alloys, and this advantage can be maintained to 500 / C or so, so some titanium suitable for manufacturing gas turbine components.
