Nickel superalloy analysis by ICP-MS according TO E2823

Nickel-based superalloys are used in environments that place high demands on materials: high temperatures, corrosion, oxidation, fatigue, and creep. Their performance depends directly on controlling their chemical composition, from alloying elements to constituents present at low concentrations. A deviation in composition can affect mechanical properties, weldability, processability, or the compliance of a material supply.

Filab laboratory supports industrial companies in the chemical characterization of their nickel alloys, whether to inspect incoming material, qualify a production batch, investigate a non-conformity, or compare a material with a specification. This approach complements the support offered to foundry industry professionals.

ICP-MS is a suitable technique when control focuses on low-level elements in a complex nickel-based matrix. It helps document an alloy's composition, verify consistency with a specification and support the analysis of deviations observed during manufacturing or service.

Filab laboratory can integrate this analysis into a broader characterization strategy, combining it with other material tests where necessary. To structure an investigation or secure a development project, also discover our industrial process audit support.

Filab laboratory examines parts, coupons, chips, powders, wires, bars, sheets and other forms compatible with preparation and analysis operations. Sending a sufficient quantity of material and clearly identifying each sample helps ensure test representativeness.

When analysis concerns a specific area, such as a weld, heat-affected zone or fracture area, this information should be specified when the request is submitted. Filab laboratory can then propose preparation procedures consistent with your requirements.

The test report states the results obtained for the requested elements, using the agreed units and providing the information required for their use. Comparison with a compliance requirement depends on the specification supplied by the contracting party, the applicable material standard or the criteria established for the project.

Filab laboratory prioritizes reporting adapted to the needs of quality, materials, purchasing, production and R&D teams. Results can therefore support batch release, supplier assessment, process monitoring or the investigation of a non-conformity.

Analysis of nickel superalloys by inductively coupled plasma mass spectrometry, or ICP-MS, makes it possible to determine the elements targeted by the ASTM E2823 method following appropriate sample preparation. The method is part of a demanding analytical control process for alloys intended in particular for aerospace, energy, chemical, thermal equipment, and industrial process applications.

At Filab laboratory, the analytical program is defined according to the grade, matrix, elements to be monitored, and acceptance criteria provided by the customer. Results are presented in a report that can support your quality control, material qualification, or expert assessment decisions.

Result quality depends on the sample's representativeness and its dissolution. Sampling, cutting, grinding and preparation procedures are defined according to the part's geometry, the presumed homogeneity of the material and the purpose of the analysis.

At Filab laboratory, preparation is adapted to the metallic matrix to limit the risk of contamination, analyte loss or matrix effects. Information about the grade, metallurgical condition, any surface treatment and the area to be inspected helps secure the interpretation.

The analytical requirement is established from your specifications: declared grade, internal specification, applicable standard, elements to be sought, decision thresholds and reporting units. This step makes it possible to select the relevant analytes and confirm that the ASTM E2823 method is suitable for the intended objective.

For comparative testing or expert assessment, it is also useful to provide available reference values, batch history and the industrial context of the anomaly.

Chemical analysis is an essential decision-making tool, but it may need to be considered alongside manufacturing history, operating conditions and observed performance. In the event of a deviation, Filab laboratory can help define additional investigations suited to the material and suspected mechanism.

This approach is particularly useful for distinguishing between a change in composition, material heterogeneity, contamination or a process-related deviation.

To prepare your request, provide the alloy designation, the form and quantity of the samples, the elements to be measured, the target method or specification, and the expected thresholds. Specify the context of the request: incoming material inspection, production control, supplier qualification, anomaly investigation, or development project.

Contact the Filab laboratory to assess analytical feasibility, define the appropriate control plan, and obtain a technical proposal. Send your samples with their identification and the information required to ensure the tests are carried out correctly.
