Nb-Hf Alloys, TIG Weldment, 2T bend.


The requirement for high-performance, lightweight space propulsion systems has prompted rapid investigation of refractory metals that are capable of withstanding high stress levels at elevated temperatures, and also have a low ductile-to-brittle transition temperature for withstanding high frequency vibrations at cryogenic temperatures. The metals which demonstrate these requirements are the Niobium based alloys. C-103 niobium was selected to satisfy initial design requirements because of its excellent fabricability. C-103 niobium is considered the most "forgiveable" Niobium alloy from the standpoint of welding and spinning. Hardware which has had as much as 600" of TIG weldments formed after welding and coating has withstood a 2T bend at -196°C (-320°F) after the unit had completed its duty cycle. Although it is considered a first-generation alloy, succeeding Nb-1 Zr, C-103 niobium was developed to replace the weaker alloys, but retain the desirable formability characteristics and welding properties. This Niobium-Hafnium-Titanium alloy satisfies most rocket engine applications for temperatures up to 1482°C (2700°F) because of superior mechanical properties at all temperatures.
