Marine Engineering Ship Ti80 Ti6Al3Nb2Zr1Mo Titanium Alloy

Ti80 titanium alloy is mainly composed of Ti-6Al-3Nb-2Zr-1Mo, which has a higher aluminum content and contains Nb stability elements, and has better comprehensive performance than titanium alloy GR5 Ti6A4V. It is widely used in Marine ships and deep-sea engineering, and is a titanium alloy material specially designed for ships.

Heat Treatment Of Ti6Al3Nb2Zr1Mo Ti80 Titanium Alloy

•  Microstructure and room temperature mechanical properties of Ti80 titanium alloy bar. With the increase of heat treatment temperature, the microstructure changes from equiaxial structure to Weissmann structure
• When plastic forming is required in the later stage, it is suitable to select the post-heat treatment process of 850℃ holding for 80 minutes and air cooling
• Through the heat treatment process of air cooling after holding at 750℃ for 80 min, the strength and plasticity of Ti80 titanium alloy bars are well matched

Application Of Ti6Al3Nb2Zr1Mo Ti80 Titanium Alloy In Ocean Engineering

There are more titanium alloy Marine materials, of which Russia is the first to use titanium alloy in ships, Among them, the commonly used types are Ti-0.3Mo-0.8Ni,Ti-3Al-2.5V,Ti-6Al-2Nb-1Ta-0.8Mo, Ti-3Al-2.5V, Ti-6Al-4V, Ti-6Al-4VELI, Ti-5Al-1Zr-1Sn-1V-0.8Mo-0.1Si, Ti-3Al-8V-6Cr-4Zr-4Mo,Ti-3Al-2Mo-2Zr(Ti75) and other high performance and high strength titanium alloys, Among them, Ti-6Al-3Mb-2Zr-1Mo titanium alloy bar has a yield strength of up to 900MPa, which is a comprehensive super strong Marine titanium alloy.

Among them, the titanium alloy pressure shell is used in the shell of the submersible, because in the process of the deep-sea pressure increase, titanium alloy has high pressure resistance, and it is the preferred material for the submersible. Because of the influence of seawater and Marine climate, the propeller used by the ship needs high corrosion resistance and fatigue resistance, and compared with other metal materials, the excellent characteristics of titanium alloy can meet the requirements of the ship’s metal materials, and the lightweight of titanium alloy can make the ship’s drive efficiency higher and the service life longer. Titanium alloy Marine propulsion equipment, which is the use of titanium alloy forgings, as well as the ship’s pipeline system device, and ordinary metal materials, titanium alloy corrosion resistance is higher. It can also reduce the weight, reduce fuel consumption, and greatly save the cost of use. Therefore, titanium alloy is an excellent all-around metal material in the ocean engineering and deep-sea ship industry.
