The growth of the additive manufacturing sector has drawn a number of companies into the metal powder supply business. In the rapid-growing additive manufacturing business, titanium alloys have steadily become the dominant materials due to their superiority over superalloys. The requirements of additive manufacturing require that titanium alloys and hightemperature alloy powders be unique in size and purity. This is to ensure high-quality and stable component production.
As the aerospace industry has grown rapidly, and especially with the advancement of high-speed vehicles and engines, there has been a significant increase in titanium alloy material demand. For aircraft that have a reduced weight or high thrust to-weight ratio, titanium alloys can be found in compressor wheels for aircraft engines, blades, integral disk disks, casings and rotors. They also play a role in missile rudders wing skeletons, cabins and engine inlets—manufacturing airway and other components. As aerospace vehicles continue to improve their performance, there are higher demands on titanium alloys’ use temperatures. The development of high temperature titanium alloys is possible.
Canadian patent-pending plasma milling technology will allow a Canadian company to manufacture high-sphericity powders of titanium alloy for use in aerospace manufacturing and the medical industry. Plasma milling will be utilized by the company to produce metal additive production powders. One of the advantages of plasma milling is its ability to create metal powders that are spherical and with high precision, controllable particle sizes, and fluidity. These characteristics closely match those of additive manufacturing. In addition, the company is developing next-generation plasmamilling equipment that will produce many additive manufacturing metals as well as composite powders.
TA32 titanium alloy, whose nominal composition is Ti-5.5Al-3.5Sn-3Zr-1Mo-0.5Nb-0.7Ta-0.3Si, is a new type of near-alpha titanium alloy newly developed. The material still remains at an elevated temperature of 550. With its good creep, long-lasting and excellent properties it can replace other steel- or nickel based superalloys. Its short-term service temperature is 600F. The material has great comprehensive mechanical properties. These include tensile strength, fatigue resistance, creep and creep.
Additive Manufacturing.
This technology uses water-cooled crucible vacuum smelting atomization gas atomization technology to finish the development of TA32 Titanium alloy powder. This technology uses electromagnetic heating to melt titanium alloy rods using a water-cooled copper furnace. The bottom injection creates the molten steel. It forms a small, stable flow through the tube. If the mixture liquid flows past the nozzle into the guide tube, the high velocity airflow created by the atomizing nostril is crushed to make fine powder particles.
After extensive testing, it was found that the TA32 titanium-alloy powder manufactured by this process has great properties. These include high purity. Several tests of the TA32’s performance were done with a particle diameter range from 15 to53m. The standard GB /T3620.1 -2016 did not specify any specific impurities. These properties were also tested. The powder has a median particle size of 36m. The bulk density is 2.4 g/cm3. It meets the needs for 3D metal printing.
You can control the laser energy density to subject TA32 aluminum alloy powder to different laser selective melting 3D printer forming tests. The metallographic analysis results demonstrated that the grain size was quite small in the TA32 powder for laser selective melting forming. Furthermore, results from mechanical testing of the test specimen showed that it had a tensile strength of 1200MPa at room temperature and an elongation value of 8%. These pieces show high-temperature tensile strength of 867MPa, 819MPa and 712MPa at 500°C. At 600°C, 550°C. and 600°C.
