Understanding the Importance of High-Temperature Alloys

High-temperature alloys are crucial components in gas turbine engines, as they enable the engine to operate efficiently and reliably. However, these alloys are prone to cracking and melting at extreme temperatures, which can lead to engine failure and increased carbon emissions. Researchers have been working tirelessly to develop new materials that can withstand these high temperatures without compromising on weight or performance.

Temperature (°F)	Current Superalloys	New Alloy
Up to 2,000	No melting or cracking	No melting or cracking
2,000 – 2,400	Melting and cracking occur	No melting or cracking
Above 2,400	Engine failure likely	Engine remains operational

The new alloy developed by ORNL and the National Energy Technology Laboratory boasts a melting point that is at least 48% higher than previously developed superalloys of nickel and cobalt. This significant improvement in high-temperature performance makes the new alloy an attractive proposition for the development of more efficient and environmentally friendly gas turbine engines.

The Challenges of 3D Printing High-Temperature Alloys

3D printing high-temperature alloys poses several challenges, including the need for precise control over the printing process and the development of specialized printing materials. The researchers at ORNL used an electron beam melting process to print test parts for the novel alloy, which required careful fine-tuning to achieve the desired microstructure and properties.

Printing Process	Challenges	Solutions
