product key technologies
Raw material preparation
Ultra high purity melting: Electron beam melting (EBM) technology is used to ensure that the purity of niobium matrix is ≥ 99.9%, the key impurity oxygen (O) content is ≤ 100ppm, the hafnium (Hf) content is precisely controlled at 9-11%, and the titanium (Ti) content is 0.7-1.3%.
Alloying control: Adding hafnium and titanium elements in a vacuum environment, achieving uniform distribution of components through electromagnetic stirring.
Hot processing forming
Squeezing and opening
Squeezing the ingot under inert gas protection at 1200 ℃ to form the initial billet.
Precision rolling
Wrap the stainless steel protective cover and roll it multiple times to a cross-sectional size of 17mm × 17mm;
The length of 500mm is achieved through temperature controlled stretching process, with a tolerance controlled within ± 0.1mm.
Core application areas
Aerospace propulsion system
- Rocket attitude thruster fuel chamber: optimized fuel flow efficiency with a 17mm × 17mm cross-section and a 500mm length suitable for compact space layout (China Aerospace Science and Industry Corporation satellite thruster);
- Small nozzle vortex ring: High temperature coating ensures structural integrity under 1700 ℃ gas erosion.
Nuclear power plant
- Reactor neutron shielding rod: 17mm square cross-section improves core space utilization and is resistant to 1300 ℃ irradiation environment.
High temperature experimental apparatus;
2. Hot press mold guide column: 500mm length meets the requirements of deep cavity molds, and its high-temperature deformation resistance extends the mold life by three times.
Technical limitations
- Oxidation sensitivity: Catastrophic powdering oxidation is prone to occur in uncoated environments at 600-800 ℃, and a protective layer of 5 must be forcibly applied;
- Processing with large aspect ratio: Rolling with a length of 500mm is prone to bending deformation and relies on precision straightening equipment for compensation.
The C103 sheet with a specification of 17mm × 17mm × 500mm is integrated through sleeve rolling and coating technology, which combines high temperature strength (1200 ℃ ≥ 85MPa) and precision structural adaptability, making it an ideal material for aerospace micro thrusters and nuclear energy shielding components. In the future, breakthroughs are needed in deformation control technology for ultra long billet rolling.
