Case Depth & Microhardness Studies

United Technical has a variety of digital microscopes and stereoscopes for both micro & macro examinations.  

With a magnification range up to 1000x we are able to analyze the microstructure of a material.  We can determine grain size, heat treat condition, analyze welds  and so much more.

Chemical Analysis 

United Technical has the ability to examine specimens at extremely high magnifications. The SEM allows for highly detailed images with excellent depth of field.  Allowing use to observe and document fracture surfaces in great detail.

 

Using EDS technology we are able to perform semi-quantitative chemical analysis of the specimens surface.

Detectors

  • Secondary Electrons

  • Backscatter 

  • EDS

Scanning Electron Microscopy with EDS Detection

United Technical utilizes  both SEM and Digital 3D imaging to analyze fracture surfaces.  Digital 3D images allow us to map and veiw large fracture surfaces.  Using Z stack technology we can view fracture surfaces with great field of depth.  Once areas of interest are determined we can pinpoint these locations for further analysis in the SEM.

Advanced Fracture & Failure Analysis Lab
