Material analysis according to AMS 2248 in the laboratory

Compliance of the chemical composition is a decisive issue for manufacturers using metal alloys, particularly when procurement requirements call for verification against a material specification. An incorrect grade, an out-of-limit content or contamination can compromise the qualification of a batch, the in-service performance of a part and the traceability of the supply chain.

The material analysis according to AMS 2248 makes it possible to compare the measured chemical composition with the limits defined for the alloy concerned. This approach helps document material receipt objectively, investigate a compliance deviation or confirm the identification of a material before processing.

The analysis covers metal materials whose composition must be verified against the applicable requirements: raw products, semi-finished products, machined parts, test specimens or samples taken from a batch. Feasibility depends on the metal matrix, the sample geometry and the chemical elements being sought.

Depending on the material and the elements expected, the Filab laboratory uses appropriate elemental characterization techniques. Sample preparation, the representativeness of the analyzed area and interference control are taken into account to obtain results suitable for compliance assessment.

To prepare a relevant proposal, provide the material designation, the applicable AMS specification, the elements or limits to be checked, the number of samples, the shape of the parts and the desired turnaround time. Material certificates, drawings and photographs facilitate the assessment of the sampling and analysis strategy.

Filab laboratory supports manufacturers in their metallurgical analysis through an approach adapted to the nature of the material, the elements to be quantified and the applicable tolerances. The analytical results are used to establish a clear comparison between the composition obtained and the requirements provided by the client.

For additional needs relating to treatment solutions, Filab laboratory also offers metallurgical bath analysis.

Before analysis, the Filab laboratory reviews the available information: alloy designation, applicable specification, material certificate, sampling area and purpose of the inspection. This step makes it possible to select sample preparation and an analytical method consistent with the thresholds to be assessed.

When the investigation requires local observation, chemical analysis can be supplemented by surface or cross-sectional examinations. The laboratory’s SEM analysis capabilities make it possible in particular to study the morphology and local distribution of elements in areas of interest.
