Titanium Superplasticity
Titanium superplasticity enables fine-grained titanium alloys to achieve high formability without necking at elevated temperatures and strain rates.
Physical-Chemical Mechanism
Titanium superplasticity occurs in fine-grained titanium alloys at elevated temperatures and specific strain rates. The alloy can deform extremely without cracking or necking.
Metallurgical Relevance & Welding Risks
This property is especially important for manufacturing complex geometric parts in the aerospace industry. If handled incorrectly or at too high strain rates, superplasticity can be lost, leading to cracks and inaccuracies.
Workshop Practice & Instructions
To utilize titanium superplasticity, temperatures during manufacturing must be precisely controlled. Strain rates should also be optimized. When welding titanium alloys, it is important to set temperatures and times such that no cracks form and superplasticity is maintained.
