The two materials testing machines were installed at the end of 2015. Key factors in the Institute’s decision to acquire the testing machines from ZwickRoell were high extensometer accuracy, precise control and the ability to define test sequences freely. The RetroLine is equipped with a temperature chamber, allowing to perform tests in a temperature range from -70°C to +200°C. In particular, strain-controlled test sequences (e.g. stress relaxation tests at temperatures up to 250°C) are conducted with the ZwickRoell testing systems in the fem laboratory.
The Z100 AllroundLine testing machine includes a high-temperature furnace and extensometer and is used for tests in air at elevated temperatures up to 1,250°C (e.g. high-temperature tensile strength test, creep strength test, determination of high-temperature shape memory properties). Materials tested include precious metal alloys, copper materials for electrical applications, samples produced by additive manufacturing processes or by investment casting.
