Ti6AL7Nb

Brief

Other name of Ti6AL7Nb: TC 20

TC20 Titanium Alloy Overview:

Nominal composition: Ti6AL7Nb

Features:

• Low density
• Appropriate strength
• Excellent biocompatibility
• Corrosion resistance
• Processability

Application in the Biomedical Field:

• Widely used as a biomedical material due to its properties.
• TC20 replaces toxic element V with non-toxic β stabilizer Nb, eliminating harmful effects on the human body.
• Long-term clinical use has gained recognition in the medical field.
• Expected to gradually replace Ti6AL7Nb titanium alloy.

Product Forms:

• Mainly available in rod form domestically.
• Increasing demand for TC20 titanium alloy sheets in the medical field.

Research on TC20 Titanium Alloy Sheet Preparation:

• Limited studies on the preparation process of TC20 titanium alloy sheets.
• Studies have shown that TC20 titanium alloy billets are rolled in the two-phase zone at temperatures ranging from 900°C to 960°C.
• Deformation control during rolling typically ranges from 50% to 70%.
• Microstructure after rolling consists of typical dual-phase structures, mainly spherical α+ intergranular β or β transformation structures.
• Grain size is generally fine in the two-phase zone rolling, meeting the standards of ETTC2’s A1 to A9 metallographic atlas.
• Exhibits excellent mechanical properties.

Challenges and Improvements:

• Conventional mechanical properties and dimensional appearance are stable in industrial production.
• Improvement potential exists in the stability of the microstructure batch.
