Material Evaluation Testing

MTEC Mechanical Testing Services is now Element

Learn more about the material evaluation testing services Element provides

  • Tension, both room and elevated temperature up to 1400° F
  • Stress rupture
  • Creep and creep rupture
  • Impact testing to -320° F
  • Fatigue testing

Test conditions can be applied to standard specimens within the capacity of the test equipment. Mechanical or electronic extensometry and related instrumentation are used as appropriate.

Fracture Mechanics Services

Fracture toughness has become a segment of the materials testing done at MTEC. Collectively, a test laboratory and a machine shop provide a complete facility for specimen manufacture, precracking and testing over a range of loading conditions and temperatures. Typical activities include:

  • Fracture toughness test (Compact Tension) per ASTM E399
  • JIC, a measure of fracture toughness test (Compact Tension) per ASTM E1290 & BS 7448

Metallography

MTEC has the facilities to provide full metallographic services. Reproducibility is achieved with automatic polishing systems. This automated system will provide large quantity sample output combined with quality surface preparation. Metallographic services include:

  • Sample preparation of all metals, alloys, coatings and electronic components plus macro and micro etching of these materials
  • Photomicrographs
  • Failure analysis
  • Microhardness testing - Knoop or Vickers
  • Microcleanliness and grain size determinations
  • Ferrite by point count with photos

Non-Destructive Testing (NDT)

MTEC has the facilities to provide full NDT services, such as:

  • Penetrant Testing (LPT, PT)
  • Magnetic Particle Testing (MPT, MT)
  • Ultrasonic Testing (UT)
  • Visual Testing (VT)

Specimen Manufacture

MTEC operates complete facilities especially planned for the manufacture of test specimens. The shop equipment is set up specifically for production of test specimens of both standard and specialized configurations. Low stress grinding and other controls are employed in manufacture to ensure a high degree of uniformity.


Test Material Heat Treatment

  • Temperature capabilities up to 2,300° F with furnace uniformity of + or - 5° F. - water and oil quenched
  • To ensure test material is heat treated in accordance with requirements, calibrated check thermocouples are used with each furnace load
