To address the limitations of the Ti-6Al-4V alloy, scientists have successfully developed new titanium alloys such as Ti6Al-7Nb, Ti-13Nb13Zr, and Ti-12Mo6Zr. These alloys retain the excellent properties of titanium while avoiding the release of harmful elements, offering a safer option for permanent implants.

Heat treatment is crucial for enhancing the performance of GR20 titanium alloy. The common heat treatment processes include annealing, solution treatment, and aging treatment.

The primary methods for straightening titanium rods, wires, and tubes include tension straightening, sinusoidal straightening, and pressure straightening.

TC4 and TC6 titanium alloys have significant differences in chemical composition, microstructure, mechanical properties and application fields.

The chemical composition of ‌TC4 ELI titanium alloy is similar to TC4, but has lower aluminum and oxygen content ‌, giving it a higher purity and lower oxygen content, thus improving its corrosion resistance and biocompatibility.

With the continuous progress of global medical technology, medical titanium alloy, as a metal material with excellent biocompatibility and mechanical properties, is increasingly widely used in implantable medical devices and artificial joints. This report aims at a comprehensive and in-depth analysis of the market status, development trends and investment prospects of medical titanium alloy bars.

The thermal conductivity of titanium rod and titanium alloy rod blank is relatively low, which is particularly significant in the process of hot extrusion. Due to the lack of thermal conductivity, there will be a great temperature difference between the surface and the inner layer of the billet. Especially when the temperature of the extrusion cylinder is set at 400 degrees, this temperature difference may even reach 200 to 250 degrees. The effect of inspiratory strengthening and the temperature difference of billet cross section lead to significant difference in strength and plasticity of metal on billet surface and center. This difference will cause uneven deformation in the extrusion process, resulting in a large adjoint stress in the surface layer, which is the main reason for the formation of cracks and cracks on the surface of extruded products.

The selection and development of aviation materials is crucial to the manufacturing cost and overall performance of aircraft airframe structures. Looking back at history, China mainly relied on the introduction of aviation equipment in the early days, so the material system is mostly in use of foreign standards. However, in recent years, China has made remarkable progress in aviation new material technology, but it still needs to face the gap with the international advanced level.

Hardness is a key index to measure the ability of material to resist plastic deformation, and has a direct effect on the wear resistance and service life of the alloy. TA9 titanium alloy is a kind of high performance alloy material, its hardness properties are closely related to its microstructure, alloying element content and heat treatment process.

In the field of metal materials processing, titanium and titanium alloys are widely used in aerospace, medical, chemical and other fields because of their excellent physical and chemical properties. In order to meet the demand for titanium and titanium alloy bars, wires and profiles in different fields, in addition to the common forging production method, the pass rolling method has also become an important production method for such materials with a diameter of less than 100mm. In this paper, the pass rolling technology and characteristics of titanium alloy bar, wire and profile are introduced in detail.

In the field of healthcare, medical titanium rods are playing a crucial role.

With the continuous progress of medical technology, the role of medical titanium rods in clinical treatment is becoming increasingly prominent. This magical metal material has brought new hope to countless patients.
