Core material requirements for aerospace propulsion, nozzles and high-temperature structural components

In response to extreme high temperatures, high pressures and strong oxidation corrosion environments, the continuous demand for refractory metals and their related materials in aerospace propulsion, nozzles and high-temperature structural components mainly falls into the following categories. These materials are processed into various shapes to meet the functional requirements of different components.

What kind of processing will niobium-based alloys undergo when used in aerospace applications?
Niobium-based alloys are the most widely used refractory metal materials for radiation-cooled nozzle tubes. The representative brand is C-103 (Nb-10Hf-1Ti), and its core advantages lie in excellent processing ductility (able to be cold-worked into an extremely thin-walled structure with a thickness of 0.25mm) and welding performance, while the density is relatively low. In terms of shape, Nb-C103 sheet, Nb C103 rod, and Nb C103 ingot are often manufactured into conical or bell-shaped nozzle extension sections, cylindrical thrust chamber bodies, ring-shaped strengthening ribs, and thin-walled shell blanks. These shapes are achieved through spinning, stamping, or additive manufacturing, and are typically applied to the nozzle extension sections and thrust chamber bodies of liquid rocket engines.

What kind of processing will molybdenum-based alloys undergo when used in aerospace applications?
Molybdenum-based alloys are the preferred materials for medium-high temperatures (approximately 1800°C) and high structural strength requirements. Representative grades include MHC (molybdenum-zirconium-hafnium alloy) and TZM, which have extremely high recrystallization temperatures and high-temperature creep resistance. The MHC alloy achieves dimensional stability in the nozzle throat region of 1800 to 2200°C by forming HfC/ZrC dispersion strengthening phases, and its thermal shock resistance is superior to pure molybdenum. In terms of shape, molybdenum-based alloys are often processed into ring-shaped throat liner segments, cylindrical or conical high-temperature connectors (bolts, pin shafts), hexagonal cladding tubes for nuclear reactors, thin-walled cylindrical structural components, and fasteners with internal threads. These shapes are formed through forging, rolling, machining, or powder metallurgy and are suitable for rocket engine nozzle throat liners, high-temperature connectors, and high-temperature structural components for nuclear reactors.

What kind of processing will tungsten-based alloys undergo when used in aerospace applications?
Tungsten-based materials are the core materials for high-temperature resistance (above 3000°C) and are crucial in the highest temperature ranges. They include pure tungsten, tungsten-copper, tungsten-silver, and tungsten-rhenium alloys. Due to their extremely high melting point (3422°C) and high temperature strength, as well as the unique "spontaneous sweat cooling" mechanism (such as tungsten infiltration with copper), these materials are widely used. In terms of shape, tungsten-based materials are often made into conical or double-arc-shaped throat liners, disc-shaped gas turbines, sharp wedge-shaped leading edges of hypersonic aircraft, cylindrical or square anti-ablation blocks, thin-walled tubes, and complex irregular parts with cooling channels. Among these, tungsten-copper throat liners are typically made by first powder metallurgy to form a porous tungsten framework (in the form of rings or sleeves), and then infiltrating copper to form a spontaneous sweat cooling structure. These shapes are widely used in the throat liners of solid rocket engines, gas turbines, and the leading edges of hypersonic aircraft.

What kind of processing will rhenium and platinum undergo when used in aerospace applications?
Rhenium and platinum group metals are used as special high-performance coatings and key component materials. The representative forms are pure rhenium and iridium coatings. Rhenium has excellent room-temperature plasticity and does not react with carbon to form brittle carbides, making it the most ideal compatible coating material for carbon/carbon composite materials. Iridium is an excellent anti-oxidation layer. In terms of shape, pure rhenium is often made into thin-walled cylindrical nozzles, conical bushings, irregular crucibles, as well as wire or foil materials; the coatings of iridium and rhenium are uniformly thin layers covering the substrate surface, with a thickness usually ranging from several tens to several hundred micrometers, and the shapes are perfectly matched to the substrate (such as the inner walls of trumpet-shaped nozzles, spherical thrust chambers). These shapes are mainly used for high-temperature anti-oxidation coatings of rocket thrust chambers and high-performance spacecraft nozzles.

What kind of processing will Nickel-based and cobalt-based undergo when used in aerospace applications?
Nickel-based and cobalt-based superalloys are the main engineering materials in the medium and low-temperature range (below 1200°C), balancing cost and performance. Representative grades include Haynes 230, Inconel 625, and L-605. They possess excellent high-temperature strength, oxidation resistance, and mature manufacturing processes, with costs significantly lower than those of refractory metals. In terms of shape, the components of these alloys are extremely diverse, including large bell-shaped nozzle extension sections (which may contain hundreds of rectangular or circular regenerative cooling channels), annular combustion chamber walls, cylindrical or conical transition sections, turbine discs (with complex blade-shaped grooves), thin-walled shells, corrugated heat shields, flanged cylindrical connectors, and various special-shaped supports and conduits. These shapes can be achieved through casting, forging, sheet metal stamping, pipe bending, or additive manufacturing, and are widely used in large nozzle extension sections, regenerative cooling channel walls, and attitude control engine nozzles.

What kind of processing will Carbon/carbon and ceramic matrix composites undergo when used in aerospace applications?
Carbon/carbon and ceramic matrix composites are the preferred materials for achieving extreme lightweighting and ultra-high specific strength. The representative materials are C/C and C/SiC, which have extremely low density (approximately 2.0 g/cm³) and extremely high high-temperature strength and thermal shock resistance. In terms of shape, these materials are often manufactured into large bell-shaped or conical upper stage nozzles, wing-shaped or wedge-shaped missile control surfaces, flat or curved panel-shaped high-temperature protection systems, cylindrical combustion chamber liners, conical diffusion sections, and complex thin-walled components with reinforcing ribs. These shapes are typically produced through chemical vapor infiltration, precursor impregnation and pyrolysis, or carbon fabric layup followed by molding. They are mainly applied to large liquid rocket upper stage nozzles, missile control surfaces, and high-temperature protection systems.

What kind of processing will Ta-10W undergo when used in aerospace applications?
The most important application of Ta-10W in liquid rocket engines is to manufacture the body of the thrust chamber and the lining of the combustion chamber. These components directly withstand the high-temperature impact of the gas. Ta10W sheets and Ta10W rods are often processed into corresponding shapes and used in aerospace applications.

The demand for the above six types of materials in aerospace propulsion, nozzle systems and high-temperature structural components is not only related to the properties of the materials themselves, but also to the fact that they can be processed into various shapes ranging from simple rotary bodies (cylinders, cones, rings) to complex irregular parts (cooling channels, control surfaces, blade-shaped grooves), in order to meet the requirements of different temperature ranges, different loads and different manufacturing processes.
