Titanium Hydride Embrittlement

Titanium hydride embrittlement is the absorption of hydrogen into titanium, forming brittle hydrides and leading to failure. Purity during processing is critical.

Physical-Chemical Mechanism of Action

Titanium hydride embrittlement occurs when hydrogen enters the titanium lattice and forms hydrides. This changes the crystal structure and makes titanium more brittle.

Metallurgical Relevance & Welding Risks

Embrittlement can lead to sudden cracking and failure under mechanical stress. It's especially prevalent at high temperatures and long exposure times in hydrogen environments.

Shop Practice & Action Instructions

To avoid embrittlement, strict cleanliness of titanium parts during processing is essential. Use clean welding consumables and control temperature and time in hydrogen environments.
