Do you need to perform an analysis of refractory metals according to ASTM E1941?
Securing Metallic Materials for the Aerospace & Defense Sector with ASTM E1941
In the Aerospace, Space, and Defense (ASD) sectors, material mastery is not an option, it’s a necessity. Even the slightest non-conformity can have major consequences on safety, performance, and regulatory compliance.
ASTM E1941 meets this high standard. It defines a rigorous analytical framework for determining carbon content in refractory and reactive metals an element whose concentration directly impacts microstructure and mechanical properties.
At FILAB, we support manufacturers in the ASD supply chain with the characterization and testing of their materials according to ASTM E1941. Our goal is clear: to ensure the reliability of your technical and industrial decisions.
ASTM E1941: a key challenge for refractory and reactive metals
Carbon Analysis according to ASTM E1941
The ASTM E1941 standard defines a standardized test method for the determination of carbon in reactive metals (Titanium, Zirconium...) and refractory metals (Tungsten, Molybdenum, Tantalum...) by combustion in an oxygen stream.
It is specifically used to:
- Measure carbon content with high precision (from ppm levels to percentages).
- Control the purity and metallurgical quality of high-tech alloys.
- Verify compliance with regulatory standards and client specifications.
In the Aerospace and Defense industries, carbon is an interstitial element that has a direct impact on:
- Mechanical properties (increased hardness, risk of embrittlement)
- Weldability of components
- Service life of parts subjected to high stress
ASTM E1941 is therefore essential for material qualification, quality control (QC), supplier validation, or failure analysis following a non-conformity.

Our FAQ
It primarily applies to reactive metals (Titanium, Zirconium, Hafnium) and refractory metals (Molybdenum, Tungsten, Tantalum, Niobium), as well as their respective alloys used in critical environments.
This standard provides for the quantitative determination of carbon. If present in excessive amounts, this element can alter the metal's crystal structure and significantly impair its ductility.
ASTM E1941 relies on combustion analysis in an induction furnace under an oxygen stream. The carbon is converted into CO2, which is then measured by high-precision infrared (IR) detectors.
- Qualification of raw material batches.
- Quality control following additive manufacturing or heat treatment processes.
- Failure analysis on parts exhibiting abnormal brittleness.
- Support for aerospace certification dossiers.
While oxygen (covered by ASTM E1409) is the primary interstitial gas monitored for Titanium, carbon plays an equally decisive role. Monitoring carbon is essential to ensure the absence of brittle carbides, particularly in refractory metals and during high-temperature manufacturing processes.
