Titanium Interstitial Lattice Distortion
Titanium interstitial lattice distortion occurs when small foreign atoms are incorporated into the hexagonal crystal lattice of titanium. This increases yield strength but reduces elongation at break.
Physical-Chemical Action Mechanism
Titanium interstitial lattice distortion occurs when oxygen, nitrogen, or carbon penetrate the hexagonal crystal lattice of titanium. These foreign atoms distort the lattice and affect its mechanical properties.
Metallurgical Relevance & Welding Risks
The distortion can increase the yield strength, which improves strength. However, elongation decreases, leading to increased susceptibility to cracking. Incorrect handling during welding can result in unwanted mechanical properties and reduced component lifespan.
Workshop Practice & Instructions
To minimize the negative effects of titanium interstitial lattice distortion, it is important to maintain a clean welding environment and correct welding parameters. Avoid excessive temperatures and rapid cooling, as this promotes the incorporation of foreign atoms. When selecting titanium material, pay attention to the oxygen, nitrogen, and carbon content to achieve an optimal balance between strength and elongation.
