This document specifies the mandatory storage and handling conditions for the TI31 titanium alloy powder. These protocols prevent powder contamination and early oxidation during laboratory use.
- Anhydrous Storage: Store the powder under anhydrous, gas-regulated conditions to prevent moisture uptake.
- Inert Gas Handling: Handle the powder exclusively within dry, inert gas environments to avoid oxidation.
- Container Sealing: Keep the container tightly sealed when not in use to maintain powder purity.
Follow these steps to safely handle and store the titanium alloy powder. These actions prevent contamination and maintain material integrity.
- Inspect Container
Inspect the container for any damage or leaks before use. - Transfer to Inert Atmosphere
Place the container inside an inert gas filled glovebox before opening. - Open in Inert Environment
Open the container only within the inert environment to maintain anhydrous conditions. - Reseal After Use
Reseal the container tightly after each use to prevent oxidation.
What elevated-temperature mechanical properties does the Ti31 titanium alloy powder maintain after heat treatment?
The Ti31 powder achieves a tensile strength of ≥540 MPa, yield strength ≥460 MPa, and elongation ≥20.0% at 250°C, and retains tensile strength ≥480 MPa, yield strength ≥370 MPa, and elongation ≥20.0% at 350°C. These metrics are specified for post-heat-treatment conditions, confirming its suitability for high-temperature components such as heat exchangers and condensers.
What particle size distribution and sphericity are specified for SLM processing of Ti31 powder?
The powder has a particle size range of D10 ≥15 μm, D50 30–40 μm, and D90 ≤63 μm, with a sphericity threshold of ≥0.9. These characteristics ensure smooth bed delivery and consistent layer deposition in selective laser melting (SLM) systems, as confirmed by the flowability of ≤35 s per standard measurement volume.
What storage and handling conditions are required to prevent contamination or oxidation of Ti31 powder?
The powder must be stored and processed under anhydrous, gas-regulated laboratory protocols, with containers tightly sealed or handled exclusively in dry, inert gas environments. This prevents oxygen interaction and early oxidation, preserving the powder's technical purity and interstitial element control (e.g., O ≤0.15 wt.%) before melt validation.
Atomfair Ti31 titanium alloy powder (1 kg, 15–53 μm) is a spherical SLM-grade feedstock with a minimum sphericity of 0.9, tightly controlled interstitials, and post-heat-treatment room-temperature tensile strength ≥720 MPa, while maintaining ≥20% elongation at 350°C. It is formulated for corrosion-resistant chemical processing and marine components, but requires anhydrous, inert-gas handling and sealed storage to prevent oxidation and moisture uptake.
Positive
- High sphericity and flowability: Sphericity ≥0.9 and a flowability of ≤35 s per standard volume support consistent powder bed deposition in automated SLM tracks, reducing layer-to-layer variance.
- Elevated-temperature ductility retention: Post-heat-treatment elongation remains ≥20.0% at 350°C, with tensile strength ≥480 MPa, providing a durable safety margin for components operating under elevated thermal loads.
Trade-offs
- Strict inert-gas handling required: The powder must be processed and stored under anhydrous, gas-regulated conditions; exposure to ambient oxygen or moisture can cause contamination or premature oxidation before melt validation.
- Sealed storage and dry environment: Containers must remain tightly sealed and be handled exclusively in dry, inert gas environments to preserve chemical purity and prevent interstitial pickup, which could affect final part mechanical integrity.
