This document outlines the environmental and processing constraints for the ATOMFAIR® IN718 nickel superalloy powder. It is intended for researchers using the powder in additive manufacturing processes.
- Anhydrous Atmosphere Requirement: The powder must be stored and handled exclusively under an anhydrous inert gas environment to prevent surface oxidation and phase contamination.
- Sealed Container Integrity: Keep containers tightly sealed when not in use to halt surface oxidation.
- Processing Compatibility: The powder is optimized for Selective Laser Melting (SLM) and Laser Solid Forming (LSF) processes.
- Thermal Validation Precondition: Avoid any ambient exposure before thermal validation to prevent degradation.
How do the particle size characteristics (D10, D50, D90) of ATOMFAIR IN718 powder impact its flowability and packing density in SLM and LSF processes?
The powder has a particle size distribution with D10 ≥15 μm, D50 30–40 μm, and D90 ≤60 μm, combined with a sphericity ≥0.9 and flowability ≤18 s/50g. These parameters ensure apparent density ≥4.4 g/cm³ and tap density ≥5.0 g/cm³, which minimize layer voids and promote consistent deposition in SLM and LSF systems.
What mechanical properties can be expected from ATOMFAIR IN718 after standard heat treatment and aging, particularly at elevated temperatures?
At room temperature, the heat-treated and aged alloy delivers tensile strength ≥1300 MPa, yield strength ≥1100 MPa, and elongation ≥15%. At 650°C, tensile strength remains ≥1000 MPa with yield strength ≥900 MPa and elongation ≥12%. Stress rupture testing at 650°C and 690 MPa shows a duration ≥30 h with elongation ≥5%, confirming high-temperature endurance.
What are the critical storage and handling conditions for ATOMFAIR IN718 powder to prevent oxidation and phase contamination?
The powder is sealed in heavy industrial vials blanked with high-purity argon gas to halt surface oxidation. It is highly sensitive to ambient exposure; containers must remain tightly sealed or be handled exclusively within an anhydrous inert gas environment to prevent phase contamination or degradation before thermal validation.
Atomfair IN718 gas-atomized spherical powder provides a Ni-Cr-Fe matrix with niobium-modified aging response, ≥0.9 sphericity, and ≥1000 MPa tensile strength at 650°C for SLM and LSF workflows, but requires argon-blanketed storage and inert handling to preserve powder quality before thermal validation.
Positive
- High-temperature strength retention: The IN718 matrix maintains tensile strength ≥1000 MPa and resists creep under sustained 650°C loading, supporting use in elevated-temperature aerospace and rotating machinery components.
- Consistent spherical powder flow: Sphericity ≥0.9 and flowability ≤18 s/50g promote uniform layer deposition and reduce void formation during SLM/LSF powder spreading, supporting repeatable part density.
Trade-offs
- Strict inert-gas handling required: The powder is highly sensitive to ambient exposure; containers must remain tightly sealed and any handling should occur in an anhydrous inert-gas environment to prevent surface oxidation and phase contamination prior to thermal processing.
- SLM/LSF process envelope: Optimization is stated only for selective laser melting and laser solid forming; users pursuing alternative additive manufacturing routes must independently validate powder performance on their own equipment.
