The high demands that are placed on the material are reflected in the demands of the materials testing systems. With the procurement of each individual testing machine for expanded creep and fracture tests up to 1,600°C, IPM was required to make an open bid invitation. ZwickRoell won in the end, not only due to the positive experiences that IPM already had using ZwickRoell materials testing machines, but also due to the technical specifications when compared to the competition.
At the same time, reaching the required temperatures up to 1,600 °C in an argon inert gas atmosphere within a vacuum chamber played a large role in winning the bid, as did the precise and constant temperature, force, and strain control as well as standard-compliant axial alignment.
Due to being equipped with the respective high-temperature resistant tools, tensile as well as compression tests can be performed with the ZwickRoell creep testing machines. The ease with which tools can be changed and the interchangeability between the testing machines provide IPM another benefit. Using a high-temperature resistant extensometer, the strains are measured directly on the specimen with a resolution of 0.1 µm.
In order to examine the extreme operating conditions for new materials in creep and fracture applications, simple test stands are no longer sufficient, rather complex test setups are increasingly gaining significance. With the acquisition of the ZwickRoell creep testing machines, we are now aptly equipped, states Ing. Petr Dymacek, Ph.D.
