Determination of chemical composition of metals and alloys

Methods for chemical composition analysis:

  • Spectral analysis (Atomic Emission Spectroscopy – AES)
  • SEM-EDS – Scanning Electron Microscopy with Energy Dispersive Spectroscopy 

Chemical composition is analysed mainly during conformity evalution to determine metals and their alloys actual chemical composition more precisely their chemical elements concentration.

Structural analysis of metals and alloys

Microstructure analysis methods:

  • Steel grain size EN-ISO 643
  • Steel non-metallic inclusions ASTM E45

 

Macrostructure analysis tests: 

  • Fracture surface analysis
  • Porosity
  • Micro/macro cracks
  • The purpose of structural analysis of metals and their alloys is to evaluate material conformity to requirements and to assess heat treatment quality. Metals and alloys cleanliness (different inclusions), grain size and microstructure are evaluated. 
  • The purpose of fracture surface analysis is to identify the nature of fracture – brittle or ductile and root cause of failure for example overload, corrosion etc.

Light optical microscope optical magnification is between 4,7x … 1000x. In case of need, using scanning electron microscopy (SEM) enables using higher magnifications (up to 20.000x). 

For microstructure analysis, preparing a cross-section from examined sample is needed. For that, sampled material is encapsulated with mounting with a plastic shell which prepares the sample for the following metallographic grinding, polishing and etching steps. Both, hot and cold mounting are available (cross-section diameter 25 mm … 50 mm).

LOM and/or SEM methods are used for macrostructure and fracture surface analysis.

Expertise and consultations

We offer a professional expertise work because we are used to the high demands of companies and have understanding of several production processes.

 

We also offer consultations and can assist in improving the production process and performing quality control of production. We have long-term experience of cooperation with industrial companies

Expertise is mostly used in finding out the reasons for the breakage or failure of parts or the processes. Expertise is not only performed to resolve disagreements between the parties, but also in situations where the manufacturer or the user of the product examines some product-related process or product characteristic:

  • causes of breakage/wear of one particular part;
  • fast machine part, etc., which occurred as a result of repair or reconstruction;
  • breakage/wear; causes of scrap parts in production;
  • the suitability/properties of the material used or applied.

When ordering expertise, the following circumstances must be taken into account:

  • the expertise is performed on a specific material/detail brought by the customer;
  • studies and opinions performed in expert examination must remain within the competence of the laboratory;
  • it is not possible to answer all questions unambiguously.
