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 to determine grain size, evaluate heat treat condition, analyze welds and much more.
​​
Metallographic Analysis
Using advanced Glow Discharge Spectroscopy we are able to determine the chemical composition of a variety of base metals:
-
Low-Alloy Steel
-
Tool Steel
-
Stainless Steel
-
Cast Iron
-
Aluminum
-
Copper
-
Nickel
Chemical Analysis
Our SEM provides highly detailed images with excellent depth of field at ultra-high magnification to observe and document fracture surfaces in great detail.
Using EDS technology we are able to perform semi-quantitative chemical analysis of the specimen's surface.

Scanning Electron Microscopy with EDS Analysis
Utilizing both SEM and digital 3D imaging, we analyze all aspects of fracture surfaces. Digital 3D images allow us to map and view large fracture surfaces. Using Z-stack technology, we can view fracture surfaces with great field of depth. Once areas of interest are pinpointed, we perform further analysis in the SEM.
Advanced Fracture & Failure Analysis
United Technical has three tensile frames each with different capabilities to fit your project needs.
​​
-
Our new MTS Landmark frame can perform tensile, compression and fatigue testing up to 100 ksi.​
​
-
Our large Rehlie hydraulic tensile frame with new digital load cell is capable of testing both tension and compression up to 300 ksi​
​​
-
Our small ATS frame is used for small specimens with loads under 10 ksi
