The differences between GR5 titanium alloy and GR23 titanium alloy

GR5 titanium alloy is an α-β titanium compound effectively developed in the United States in 1954. It contains 6% alpha-equilibrating component and 4% beta-settling component V. The surface synthesis of GR5 titanium compound is 7.0 aluminum, 2.9 molybdenum, and contains 10%-15% beta work in the strengthened state. Al further develops the combined room temperature strength and warm strength properties by gradually strengthening the strong arrangement of α in the Ti-Al-V framework, while V is one of the few composite components in titanium compounds that can both increase strength and further develop flexibility. . Because it does not increase the c/a axis ratio of the γ state lattice like most alloying elements, V has a beneficial effect on the plasticity of titanium alloys. Conversely, V reduces the ratio, thereby improving phase formation and avoiding long-term use. Alloy embrittlement can occur during the interaction.
Its main features are excellent overall performance and excellent cycle performance. It has moderate room temperature and high temperature strength, good impact resistance and thermal reliability, high weakening resistance and fracture diffusion resistance in seawater, and acceptable crack durability and protection against thermal salt pressure consumption . In addition, it is less sensitive to hydrogen than GR2 and GR1 alloys and can be used to manufacture a variety of parts operating in a wide temperature range from -196°C to 450°C, especially those designed according to damage tolerance limit principles . It also offers excellent cycle versatility and superplasticity, allowing it to be used with frames using different tensioning strategies, as well as being welded and machined in different ways.

Its main semi-finished products include bars, forgings, thin plates, thick plates, profiles, wire rods, etc., in addition to castings (ZTC4).

GR23 is a better improvement of GR5. Its main difference is the different Al content and the lower content of interstitial components Fe, N, H and O.

It has become a clinical precision implant material due to its good biocompatibility, low elastic modulus, low thickness, corrosion resistance, non-toxicity, high recovery strength, long wear life, high flexibility at room temperature, and simple structure. . . The best material for things. Clinical GR23I titanium alloy composite plates are mainly used for skull fixation, bone grafting, etc., and have high requirements on strength, fatigue life, versatility, etc.

Titanium alloys are based on titanium with other elements added. Titanium has two homogeneous gemstones: Titanium is an isomer with a softening point of 1668°C. It has a nearly filled hexagonal cross-section structure below 882°C and is called α-titanium; it is a volume-focused cubic structure above 882°C. The fret structure is called beta-titanium. By combining the various properties of the above two structures with appropriate alloying elements and gradually changing the phase transformation temperature and component content, titanium alloys with different structures can be produced.

It is based on GR5 alloy and reduces the content of interstitial components C, O, N and contaminating component Fe. The strength has been reduced, but the durability can be improved to a higher level. It has good flexibility, solidity, good welding performance and low temperature performance, and is widely used in important fields such as low temperature design, clinical research, ships and aircraft.

GR5 titanium alloy material can be used in typical or high temperature conditions, and GR23 alloy can be used in ultra-low temperature conditions.

The following are similar grades of two titanium alloys: T-6A-4V/Grade 5 (American grade), BT 6 (Russian grade), IMI 318 (British grade), TiAI6V4 (German grade).

Clinical hardware manufacturing: titanium and titanium composite materials are used to produce false joints, bone plates and screws, which are used for bone and joint trauma caused by human injuries and cancer, and are currently widely used in clinical settings. Also used for hip joints (including femoral heads), knee joints, elbow joints, metacarpophalangeal joints, interphalangeal joints, mandibles, prosthetic vertebrae (spinal orthoses), pacemaker shells, prosthetic hearts (heart-shaped valves), dentures Inserts, titanium-nickel titanium mesh in orthodontics and cranioplasty medical procedures, etc.

Titanium and titanium composite materials have attracted increasing attention due to their high specific strength, biocompatibility and huge consumer prospects. Protection of body fluids.

Ti 6Al-4V ELI is a grade of Ti 6Al-4V with a more modest underlying pore size for the most extreme durability and is suitable for seawater and cryogenic conditions. This grade of amalgam is usually used in the toughened state. Ti 6Al-4V is a premium decision-making material in the field of clinical inserts.

The manufacturing process is: 900-120 degrees Fahrenheit, moderate unwinding and strengthening for 1-4 hours, air cooling. Double strengthened, round bars and forgings are aligned and toughened at a beta temperature of 50-100 degrees Fahrenheit, held for no less than 60 minutes, then air cooled, then heated at 1300-1400 degrees Fahrenheit, held for approximately 60 minutes, then air cooled . Relaxation annealing should be performed after welding.
