We’re celebrating getting to the “fringe” of the weekend with a Heat Treat Fringe Friday covering news about the promise gallium nitride (GaN) for the future of missions to Venus. Specifically, how this high-temperature-defying material may be used to form semiconductors that won’t melt on the near 900°F surface of Venus.
While not exactly heat treat, “Fringe Friday” deals with interesting developments in one of our key markets: aerospace, automotive, medical, energy, or general manufacturing.
Gallium nitride is a material that researchers at the Massachusetts Institute of Technology (MIT) have been studying how it performs when exposed to high temperatures. They have recently announced that their research has shown successful performance results at 500°C for 48 hours.
The surface of Venus can reach temperatures of up to 480°C. With silicon-based electronics incapable of operating at these high temperatures or a long duration of time, finding a material that can take the heat becomes critical to prospect of sending a rover to the planet’s surface.
John Niroula, an electrical engineering and computer science (EECS) graduate student and lead author of the paper, commented, “Transistors are the heart of most modern electronics, but we didn’t want to jump straight to making a gallium nitride transistor because so much could go wrong. We first wanted to make sure the material and contacts could survive, and figure out how much they change as you increase the temperature. We’ll design our transistor from these basic material building blocks.”
Funding of this research has come from numerous interested parties, including the U.S. Air Force Office of Scientific Research, Lockheed Martin Corporation, the Semiconductor Research Corporation through the U.S. Defense Advanced Research Projects Agency, the U.S. Department of Energy, Intel Corporation, and the Bangladesh University of Engineering and Technology.
NASA has selected Elementum 3D (a developer and supplier of metal additive manufacturing (AM) advanced materials, print parameters, and services) to be one of four companies that will produce and distribute GRX-810 material under a commercial co-exclusive license. This is a material that has undergone significant post-processing heat treat research.
The 3D printable high-temperature metal superalloy material has been noted as “breakthrough technology” and will be offered to original equipment manufacturers of airplanes and rockets as well as the entire supply chain.
NASA’s goal of the licensing agreement is to accelerate the adoption of GRX-810 to benefit U.S. technologies, industry, and space exploration. The 3D printer supplier notes that engineers are eager to print with a material capable of creating lighter and thinner engine parts, reducing fuel burn, lowering operating costs, increasing durability, and lowering the tolerance for failure for critical applications.
GRX-810 is an oxide dispersion strengthened (ODS) alloy that can endure higher temperatures and stress. Its strength is derived from the dispersion of tiny particles containing oxygen atoms. The breakthrough superalloy was specifically developed for the extreme temperatures and harsh conditions of aerospace applications, including liquid rocket engine injectors, combustors, turbines, and hot-section components, capable of enduring temperatures up to 1,100°C. Compared to other alloys, GRX-810 can endure higher temperatures and stress up to 2,500 times longer. It’s also 3.5 times better at flexing before breaking and twice as resistant to oxidation damage.

Over the past nine years, Elementum 3D has gained extensive knowledge and experience in developing, commercializing, and distributing “impossible-to-print” dispersion-strengthened materials similar to GRX-810.
“We are excited to be working with Tim Smith and NASA to bring this exceptional new alloy to the commercial market,” said Jeremy Iten, chief technology officer at Elementum 3D.
NASA’s investment in developing GRX-810 demonstrates its dedication to advancing additive manufacturing. Elementum 3D and the other co-exclusive licensees now assume the responsibility of investing the time and resources to supply the industry with a stronger, more durable superalloy.
EcoTitanium, a European plant for recycling and refining titanium alloys for critical applications, was opened in France in 2017. It was the first plant in Europe to melt titanium with a cold hearth furnace – a technology that allows users to recycle titanium reverts coming from forging and machining castings from the aerospace supply chain.
The SECO/WARWICK Group was chosen as the main supplier of advanced vacuum metallurgy technology for this strategic European project, securing the creation of an autonomous European titanium channel.
Sławomir Tomaszewski, director of the Vacuum Melting Furnaces Team in the SECO/WARWICK Group, comments, “The innovative VAR furnace will increase the Partner’s production capacity and can respond to the increased demand for titanium in Europe. EcoTitanium has created the first integrated titanium processing plants in Europe, which opens the door to European, ecological, and innovative solutions for the aerospace industry. We are glad that our Group is part of this strategic project and that Retech and SECO/WARWICK brand solutions constitute the core of the machine park.”

“For EcoTitanium, we, as Retech and SECO/WARWICK, delivered two furnaces seven years ago: a plasma furnace (PAM) for consolidation and refining of titanium scrap using plasma torches operating in an inert gas atmosphere, and a VAR arc furnace for further refining of titanium ingots obtained from the PAM furnace. The current contract is a continuation of this project. We will deliver a second VAR furnace, which will significantly increase the Partner’s processing capabilities,” said Earl Good, managing director of Retech.
The new furnace’s advantage is its perfect fit into the customer’s existing infrastructure. For safe operation, VAR furnaces require complex construction work: a bunker, an explosive tunnel, as well as a dedicated control room located outside the furnace operating area.
This system is unique because current solutions in the field of furnace safety will be implemented at the design stage. These solutions result from both the experience gained by EcoTitanium and the SECO/WARWICK Group’s experience.

“The delivery of this new VAR furnace will help us to secure our customer’s growing needs for producing titanium in the context of unprecedented production ramp-ups. We are pleased to open this new chapter of EcoTitanium’s history with our long-term partner SECO/WARWICK. SECO/WARWICK has indeed offered us best-in-class solutions in the field of vacuum metallurgy technology, in particular with its PAM systems from its Retech brand, which allows us to use around 75% of recycled materials and to divide by up to four the CO2 emissions created by titanium melting,” says Jean-François Juéry, president of EcoTitanium.
Titanium, a transition metal with unique properties, is valued for its strength-to-weight ratio. It has comparable durability to steel but is 50% lighter, making it an attractive choice for industries looking for strength without additional weight. The aerospace industry consumes over 30% of global demand, and the chemical sector another 40%. Additionally, titanium has found use in medicine, especially in joint replacement procedures, dental implants, and electronics.
