What is precision titanium alloy machining?
Precision titanium alloy processing is a high-precision processing technology involving titanium alloy materials. Titanium alloys are widely used in aerospace, biomedicine, high-end manufacturing and other fields because of their high strength, low density, excellent corrosion resistance and high-temperature resistance. However, titanium alloys are complex to machine due to their physical properties, rapid tool wear, and heat treatment issues during processing.
Physical properties
Titanium alloy has high hardness and good plasticity, but its elastic modulus is low, which leads to easy elastic deformation during processing and affects processing accuracy.
Tool wear
Conventional cutting tools are prone to wear quickly during titanium alloy processing due to the material’s high strength and chemical activity, so special high-performance cutting tools must be used.
Heat treatment issues
During processing, the high chemical activity and sensitivity to heat of titanium alloys may cause reactions with oxygen, nitrogen and other elements at high temperatures, affecting material properties.
Classification grades and applications of titanium alloys
Titanium alloy is an alloy material based on titanium and added with other elements. Titanium alloys are known for their high strength, low density, excellent corrosion, and high-temperature resistance.
α type titanium alloy
This type of alloy only contains α phase and no β phase. For example, TA5, TA7, TA9, TA10. α-type titanium alloy has good corrosion resistance and weldability, but its strength is relatively low, and its high-temperature resistance is average. It is mainly used in the chemical industry, aviation and other fields, such as aircraft fuselage and engine parts.
β type titanium alloy
Titanium alloys containing beta phase. The characteristic of this type of alloy is that its strength can be greatly improved through heat treatment. For example, Ti-10V-2Fe-3Al (Ti-10-2-3), Ti-15V-3Cr-3Sn-3Al. β-type titanium alloy has excellent strength and plasticity and is often used in fields that require high strength, such as aerospace, medical equipment, etc.
α+β type titanium alloy
This type of alloy contains both α phase and β phase, which combines the characteristics of α and β type alloys. It has good strength, good plasticity and toughness. For example, Ti-6Al-4V (TC4), Ti-6Al-6V-2Sn. They are widely used in aerospace, military, biomedicine and other fields.
Near alpha titanium alloy
This alloy mainly comprises α phase with a small amount of β phase. They have good high-temperature strength and creep resistance and are often used in parts in high-temperature environments, such as blades and disks of aerospace engines.
Metastable beta titanium alloy
This alloy is mainly in the beta phase at room temperature and has high strength and good formability. They are suitable for high-performance aerospace parts.
Other notable types of titanium alloys
Such as titanium-aluminium alloy, titanium-nickel memory alloy, etc. These alloys have unique applications in specific fields, such as aviation, medical equipment, intelligent materials, etc.
