Technology ServicesMicrostructural Characterization of Materials

The materials microstructural characterization lab offers a wide range of tests for determining the composition of samples, as well as their thermal, rheological and thermomechanical properties.

Morphological and composition analyses

We can carry out the structural characterization of all kinds of materials (polymeric, metallic, ceramic, composite, etc.) by means of optical and electronic microscopy techniques.  
 
We have the right equipment to assess product quality by means of non-destructive testing (NDT, X- and UV-ray inspection) and diagnose causes of failure by means of specific defectology and fractographic analysis techniques.  
 
Different constituent detection and quantification methods allow us to perform the analysis of the composition of materials in order to determine their nature at a microscopic and a macroscopic level.
 

 

Thermal and rheological analysis

The processing and behaviour of a certain material depend on its thermal and rheological properties. We put to good use to the most powerful thermal (DSC, TGA and DMA) and rheological (MFI, dynamic and capillary) characterization techniques.

They are most commonly applied to determine melting points, crystallization and glass transition temperatures, and enthalpy and specific heat capacity. In order to predict the thermomechanical behaviour of materials, our lab is fitted with advanced DMA equipment for obtaining viscoelastic modulus curves.

Through rheological characterization we can determine the fluidity of materials and monitor curing reactions and viscosity curves.

 

 Mechanical analysis

In order to determine the energy absorption curves and the ductile-brittle transition temperature of materials, we have an impact pendulum with which to apply the Charpy and Izod methods.

By means of an instrumented hammer and advanced software, we can analyse the energy curve of materials in detail. The use of specific tools enables us to study aspects such as the heat deflection temperature (HDT) and the (VICAT) softening temperature.

We round off the mechanical analysis of materials with Brinell and Rockwell hardness and Vickers and Knoop microhardness tests.

 

 

 

Other studies

We are certified to perform tests for the characterization of some metallic materials:

  • Coating thickness measurement, as per UNE-EN ISO 2178 (Section 6.1).)

  • §Surface appearance of coatings, as per UNE-EN ISO 1461.

  • §Vickers hardness, as per UNE-EN ISO 6507-1.

In order to fully characterise materials, we employ a wide range of analyses such as viscosity in a solution, density, colorimetry, UL94 fire tests, and compression set.
