Titanium Tantalum Rod

Titanium-tantalum alloy rods are alloys of titanium and tantalum, possessing excellent high-temperature strength and resistance to high-temperature oxidation. They are primarily used in infrared camera tubes and micro-light tubes in defense night vision equipment, maintaining a long-term high vacuum state within the vacuum tube to improve equipment efficiency and imaging clarity. Their fabrication employs vacuum electron beam melting and vacuum consumable arc melting technologies. Through batch mixing of tantalum and titanium powders, combined with forging, rolling, and multi-stage heat treatment processes, a uniform microstructure with a single-phase equiaxed β structure and a grain size rating of 7.5 is formed.
