Titanium Disk

Through the comprehensive control of raw material quality and smelting process parameters, the addition of simple elements is avoided, and the kinds of intermediate alloys used are diversified and diversified, and use special intermediate alloys are tailored for titanium alloys that are easy to segregate; The melting point, density and particle size of the customized intermediate alloy are closer to that of titanium sponge, which is conducive to ensuring the composition uniformity of the mixed fabric and electrode pressing, and is conducive to reducing the risk of metal element burning and composition segregation during the melting process. Combined with the large stirring magnetic field of the VAR melting furnace and the constant temperature control cooling technology of circulating water, the macro and micro segregation can be effectively reduced, and the composition of the ingot can be guaranteed to be uniform.

TC4, TC11, TA15, TC18 and other medium and high-strength titanium alloy pipes are extremely difficult to deform due to their high deformation resistance. At present, mainly produced by forging rods + deep hole drilling machines. The material utilization rate is low, the production cost is high, and the processing cycle is long. ; Our company adopts the combination of high-temperature cross-rolling piercing + low-temperature radial forging for production. By increasing the deformation in the two-phase area and controlling the total forging ratio, obtain uniform structure and performance, low level of ultrasonic flaw detection clutter, and a maximum outer diameter of up to 350mm, high-performance titanium alloy thick-walled pipe with a length of up to 10 meters, and formed a technical invention patent "TC4 thick-walled pipe processing method", and formulated more than 10 enterprise standards. This core technology breaks through the traditional manufacturing method of medium and high-strength titanium alloy pipes. It has high efficiency and short process, low cost and high material utilization rate, and has been widely used.

Commercially pure titanium and titanium alloys show high strength, great creep and corrosion resistance combined with light weight. These mechanical properties make the material perfectly suited for use in industries that rely on high standards, such as the aerospace industry.

Titanium is used in the construction of jet engines and airframes. The alloy Ti-6Al-4V is particularly common, accounting for almost 50% of all alloys applied in the aircraft industry, which is the largest consumer of titanium.

The ship and other equipment are immersed in water for a long time, so the materials are required to have the characteristics of high corrosion resistance, safety and reliability, and long service life. Due to its wide range of strength, unique physical properties, excellent mechanical properties, corrosion resistance, and impact resistance, titanium alloys have been widely used in shipbuilding.

The titanium alloys of Russian ships are used in pumps, filters, supply pipes, fire extinguishing systems, pressure vessels, and other equipment; the Timetal 5111 developed by the U.S. Navy and Timet of the United States has good fracture toughness and anti-stress corrosion resistance, as well as good temperature, creep property and easy to weld. These high-performance titanium alloys are used in the marine systems, cooling systems, sewage treatment systems, electrical components, and other equipment of American ships.

The lightweight vehicle is one of the most promising markets for titanium. Titanium alloys are mainly used in automotive engine parts, such as connecting rods, springs, crankshafts, fasteners, etc.

Titanium alloys have been widely used in surgical implants currently. The representative titanium alloy Ti-12Mo-6Zr- 2Fe is a kind of metastable alloy, which is suitable for orthopedic devices due to its high strength and fracture toughness, abrasion resistance, corrosion resistance, and elastic modulus. The mechanical properties, corrosion resistance, and biocompatibility of titanium alloys can be improved by using alloy elements such as zirconium, palladium, niobium, tin, and tantalum, which is the main way to develop the bio-titanium alloy.
