The Journal of Materials Research and Technology, a publication of the Brazilian Metallurgical, Materials and Mining Association, has recognized the role of our Arc 200 in producing small quantities of high-purity alloys quickly and easily for testing, in its article "Rapid fabrication and characterization of AISI 304 stainless steels modified with Cu additions by additive alloy melting (ADAM)" Two quotes from the article: "Rapid alloy prototyping is quickly emerging as a manufacturing approach to design novel structural alloys, since allows producing low volume of high quality castings quickly at low cost. Thus, a large number of alloys can be produced and tested for finding the optimal composition in an alloy system. In this work, a new high throughput method for rapid alloy manufacturing has been developed and employed to cast AISI 304 stainless steel samples modified with an addition of Cu in the range of 1-4wt.%."
"The 5 alloys were processed by additive alloy melting (ADAM) under argon atmosphere in an arc furnace ARC 200 from ARCAST Inc. using a non-consumable tungsten electrode. The intensity of the electric arc is controlled by a pedal, and the maximum value can be limited in the power supply, between 0 and 600A."
Andrew Cea, of the Belgian Nuclear Research Centre, reports how he used Arcast's Arc 200 machine for the preparation of uranium-manganese alloys for microstructure and calorimetric analysis. His article in the Journal of Nuclear Materials credits this machine, and in a separate email to us, he says the scanning electron microscope images in the journal prove "how good and homogenous your samples can be".

We hope to see you at the Euro PM conference in Bilbao in October and at Formnext in Frankfurt in November. We will be visiting Euro PM and exhibiting at Formnext. The market for powder metallurgy and additive manufacturing seems to be growing at an extraordinary rate.
Arcast's supply of a 250kg capacity inert gas atomizer for research purposes to Centro de Estudios e Investigaciones Técnicas de Gipuzkoa (CEIT), San Sebastián, Spain, has made the Metal AM magazine news. Ceit is a non-profit research facility, one of whose projects is the development and improvement of powder alloys and manufacturing technologies for AM and MIM. We hope to work with CEIT's researchers to produce larger quantities of advanced alloy powders in the future. For more detail, please see the article in Metal AM Magazine.
We are looking forward to supplying a melt spinner to one of our industrial customers. It is always nice to have return customers that have been happy with other products we have supplied. With many customers, we have supplied two or three pieces of equipment. Being part of a company's (or lab's) growth and expansion into more challenging areas of materials processing, from button melters to production gas atomizer plants is rewarding.
Our best-selling, ever-growing-in-popularity product, the Arc 200, is being built and shipped out to a number of research labs. Just recently we supplied Wisconsin University, Rutgers University, and three other industrial customers.
Arcast is delighted to have the vacuum arc furnace we supplied to Imperial College in London acknowledged as equipment used to produce and cast a high-strength silicide phase in a stainless steel alloy designed for wear-resistant applications.
Hardfacing alloys provide strong, wear-resistant and corrosion-resistant coatings for extreme environments such as those within nuclear reactors. Here, we report an ultra-high-strength Fe–Cr–Ni silicide phase, named π-ferrosilicide, within a hardfacing Fe-based alloy. Electron diffraction tomography has allowed the determination of the atomic structure of this phase. Nanohardness testing indicates that the π-ferrosilicide phase is up to 2.5 times harder than the surrounding austenite and ferrite phases. The compressive strength of the π-ferrosilicide phase is exceptionally high and does not yield despite loading in excess of 1.6 GPa. Such a high-strength silicide phase could not only provide a new type of strong, wear-resistant and corrosion-resistant Fe-based coating, replacing more costly and hazardous Co-based alloys for nuclear applications, but also lead to the development of a new class of high-performance silicide-strengthened stainless steels, no longer reliant on carbon for strengthening.
Many thanks to Professor D. Dye and Dr. M Rahman from Imperial College London for allowing us access to their casting facilities to produce the carbon-deficient silicide ingot.

Arcast is excited to introduce the VersaMelt Inert Gas Atomizer.
This system will permit processing of many metal alloy systems all from a single atomizer platform. The multi-configurable melt chamber will allow:
This versatility can accommodate a wide range of complex alloys, from tin to tungsten. Clean, ceramic-free titanium (or similar metal) powders can be produced using scrap or recycled powder as feed stock. The VersaMelt has a nominal batch capacity of up to 3 kg (steel equivalent) per-cycle and multiple cycles can be performed every day.
The unit has been priced for the budgets of small companies and research establishments and was designed as a useful tool for any organisation contemplating entering the AM/3D printing arena. Arcast was particularly keen to address the issue of recycling powder wastes generated by AM processing. The system was designed to occupy minimal space (less than 4m cubed) and only requires modest services of water, gas and electricity.
In developing the VersaMelt system, Arcast has listened carefully to the comments of existing customers seeking to develop alloys and powders for the AM industry. We are confident that no other atomizing system currently on the market approaches the versatility of VersaMelt. VersaMelt is available now as a standard Arcast product. Please contact us to learn more.

See the video below for a view of one of our gas atomizers in action, our tube-feed arc/plasma melter making spherical titanium powder. The blue color results from the argon plasma. You can see a gallery of our products and processes in action here.
Arcast Inc. is proud to announce we have successfully gas-atomized titanium with a D90 of less than 60 μ (D50 of 25 μ to 35 μ) with no ceramic contact or any other risk of oxide inclusion (no contamination).
The gas-to-metal ratio is a fraction of the ratios conventionally achieved using the standard free-fall gas atomizing method. Using this method, we can start from a wide range of melt feedstocks, including but not limited to, bar, scrap or sponge. We look to combine this method with one of our continuous alloying furnaces, previously developed. The next phase of development will be to process a wide range of titanium alloys and other reactive or refractory alloys.
We believe that this is the process the industry has been waiting for: to produce low cost, clean, fine spherical titanium alloy powder very efficiently with zero risk of contamination from a wide range of economical feedstocks.
Arcast proves itself again to be a valuable player in the growing AM (additive manufacturing) and thermal spray markets by supplying to major powder producers and research centers in the USA, Europe, Australia and Africa, with prospects in Asia. We currently have a number of cold crucible furnaces and vacuum inert gas atomizers (VIGA) for metal powder production on order across America and Europe. We feel very fortunate that our hard work and dedication are being recognized across the world. Thank you to our customers new and old!
