The British company Alloyed has obtained a one million pound grant from the ATI program to boost the development of its superalloy ABD-1000AM, designed for additive manufacturing. The project, in collaboration with ITP Aero and Cranfield University, has a clear objective: to solve the persistent problem of cracking during laser powder bed fusion printing. This nickel alloy, presented to operate at high temperatures, is intended for critical components in aviation engines and gas turbines.
Tackling the Cracking Challenge in Metal 3D Printing 🛠️
The core of the project is overcoming hot cracking sensitivity, a common issue in high-strength alloys for 3D printing. The ABD-1000AM is formulated to minimize this tendency during the rapid solidification process inherent to laser fusion. The ATI funding aims to bridge the gap between laboratory research and industrial development, validating the material for use in real-world environments. The work includes optimization of printing parameters and microstructural characterization to ensure part integrity.
Because engines like heat, but not cracks 😅
It seems even superalloys have their bad days. Imagine an engineer watching an expensive part, nearly finished, decide to decorate itself with a fine network of cracks. It's the metallic equivalent of your sponge cake cracking right as you take it out of the oven, but with somewhat more expensive and less edible consequences. This grant is, basically, the budget for intensive therapy and a behavioral reform program for rebellious nickel powders. The ultimate goal is for them to withstand the heat without getting dramatic.
