Polema develops high-entropy alloy powder grades for AM

July 28, 2021

Polema, affiliated to Industrial Metallurgical Holding, headquartered in Moscow, Russia, has announced new Additive Manufacturing powder grades of high entropy alloys and Ni-Cr-Al-Y system alloys, suitable for use in aerospace and other critical industries.

The company has reported it is using gas atomisation to produce AP-CoCr23Ni26, AP-NiCr24Co24Al, AP-NiCr23Co23Al, AP-NiCr18Co18Cu20Al, AP-NiCr21Co21Mn20 and AP-NiCr20Co20Cu21 high-entropy alloy powders.

Advantages of the new materials include high corrosion resistance, ability to maintain strength and flexibility at ultra-low temperatures as well as a stable phase composition during thermomechanical treatment.

The two Ni-Cr-Al-Y system alloys, which can be used as a metal sublayer for heat-protective coatings on parts of internal combustion engines, are AP-NiCr22Al10Y (analog of Amdry 962) and AP-CrNi67Al12 (analog of Amperit 457.642). These are gas atomised and additionally alloyed with hafnium and rhenium. Previously at Polema, a reduction of oxides with calcium hydride was used for the production of Ni-Cr-Al-Y alloys.

“Polema continues to develop new types of products, which have no analogs in Russia,” commented Aleksei Filippov, CEO of the plant. “The new products will be used in aircraft construction, medicine and in other important industries.”

Powder Metallurgy: The original net-shape production process

Powder Metallurgy components are relied upon by a wide variety of manufacturing industries, from automotive to power tools, household appliances, chemical engineering, filtration and more.

The main reason for the technology’s success is its cost-effectiveness at producing high volumes of net-shape components, combined with its ability to allow the manufacture of products that, because of the production processes, simply cannot be manufactured by other methods.

To discover more about how the technology has revolutionised component production, browse our Introduction to Powder Metallurgy.
