Mechanical Properties

Material Properties

A universal testing machine to examine mechanical properties of material samples is standard equipment in most test laboratories. Our speciality is the integration of dewars or temperature chambers so we can characterize material in a wide temperature range between -269°C (4K) and 1000°C. With the ability to also integrate vacuum chambers in the testing machine, tests can even be performed in high vacuum.

Setup

The universal testing machine can be equipped with load cells up to 250 kN and a variety of tension, compression and bending setups to perform tests according to standard test specifications. We have also access to testing machines up to 10 MN. With our expertise in the development of setups and test procedures, we can also carry out individual customer-specific tests on components and systems. We are therefore constantly adapting these setups or developing new ones to meet new test requirements.

Cryogenic Charpy impact test setup down to -196°C (77K)

Cryogenic Charpy Impact Test

The selection of the best material for cryogenic applications requires a comparison of the toughness and susceptibility to brittle fracture. With our Charpy impact test the energy required to break a selected material can be determined. The test can be performed with a sample temperature down to - 77K. A Setup for charpy impact testing down to 20K is in development.
Application:
  • Cryogenic charpy impact test
  • Cryogenic charpy v-notch test
  • Cryogenic notched bar impact test
