Lower ductility/fracture toughness than austenitic 316L

Inferior weldability compared to 316L

Higher cost than 17-4PH or 316L

Lower strength than Custom 465 in peak aged condition

Overall, AerMet100 provides an optimal combination of strength, ductility, weldability, and cost for high-performance parts made by AM processes.

FAQ

Q: What are the key benefits of AerMet100 alloy?

A: The main benefits of AerMet100 are its high strength and hardness coupled with good ductility, excellent fatigue resistance, creep resistance, corrosion resistance, and moderate cost. This makes it well suited for critical AM applications.

Q: What heat treatment is used for AerMet100?

A: A typical heat treatment is 1-2 hours solutionizing at 1040-1080°C followed by air or furnace cooling to room temperature, then age hardening at 480°C for 4 hours to achieve optimal strength and hardness.

Q: What welding methods can be used to join AerMet100 parts?

A: Fusion welding methods like GTAW, GMAW, and PAW are recommended for AerMet100 to avoid cracking and minimize distortion. Low heat input and peening of welds is also suggested. Brazing can also produce good joints.

Q: How does AerMet100 compare to maraging steels for AM?

A: AerMet100 has higher ductility but slightly lower strength than maraging steels like 18Ni300 or 18Ni350. Maraging steels have poor weldability. AerMet100 is a good lower-cost alternative to maraging.

Q: Can AerMet100 be machined after AM processing?

A: Yes, AerMet100 can be machined after AM but care must be taken to account for work hardening effects. Low cutting forces, carbide tooling, and adequate coolant is recommended. Annealing may be required after extensive machining.

Q: What particle size range of AerMet100 powder is optimal for AM?

A: The recommended particle size range for AM is 15-45 μm. Finer powders improve resolution but can negatively impact flowability. Coarser powders above 53 μm can cause print defects. The typical sweet spot is 25-35 μm
