• Presented by: Peter Ruchti, ZwickRoell in Fürstenfeld, Austria
• Request for recording

A guided virtual walk through ZwickRoell Fürstenfeld's exhibition area will reveal advanced creep testing machines, high-temperature applications up to 1500 °C, and several customized solutions, one of which is a "Hot Cell Setup" for testing within a radioactive environment. As a competence centre within the ZwickRoell Group, ZwickRoell in Fürstenfeld specializes in complex requirements in this field.

Concentrated Solar Thermal Power (CSP) is a significant departure from traditional power generation as it undergoes daily cycling of temperature and pressure. Indeed, current power stations are now being operated cyclically ‘on demand’ rather than continuously at steady state. Building to current design codes, many operational CSP plants are experiencing significant stress relaxation within their systems, far beyond that predicted. CSP, due to its high temperatures and low stresses is susceptible to creep and as such it is often the limiting allowable design stress. The difficulty encountered, is that current modelling of cyclic creep i.e. transient creep, does not reflect the physical reality seen in the limited experimentation. This presentation will discuss the problem of transient creep from an experimental, modelling and design perspective for material experiencing cyclic conditions.

In this webinar, you will receive an introduction into Thermo-mechanical Fatigue Testing. You will learn which components are crucial when it comes to reliable Thermo-mechanical Fatigue Testing and how the ZwickRoell TMF test system follows the recommendations of the European Code-of-Practice. The Webinar will also show an in-phase test of an aluminium specimen in the temperature range from 100 to 300°C.

Start-up and shutdown operations, for example in gas turbines or combustion engines may induce thermo-mechanical fatigue (TMF) processes in hot-going components. Further, during steady state operation at high temperatures, oxidation and creep mechanisms may degrade the applied materials. Together, these damage mechanisms often determine the service life of the entire machines. The phase angle between mechanical strain and temperature during TMF depends on component geometry, heat input and cooling situation. The phase angle may significantly influence the acting damage mechanisms and thus the expected lifetime. Dwell times at high temperatures representing steady state operation typically reduce the TMF lifetime due to material degradation and intensified damage mechanisms. This webinar deals with the influence of phase angles and optional dwell times at high temperatures on the damage and lifetime behaviour under thermo-mechanical fatigue loading.

 This webinar demonstrates the work performed in the EU DevTMF project to identify and evaluate a range of factors influencing accuracy and comparability of data generated by three laboratories carrying out stress-controlled thermo-mechanical fatigue (TMF) crack growth (CG) tests. DevTMF (Development of Experimental Techniques and Predictive Tools to Characterize Thermo-Mechanical Behaviour and Damage Mechanisms) is a research project funded by the EU Framework Programme for Research and Innovation Horizon 2020 and Clean Sky 2 aiming at characterization of TMF behavior of two structural alloys to allow for more accurate prediction of design lives of gas turbine components. Therefore, one of the aims of the project has been to harmonize TMF CG experimental methods between the participating laboratories through a round robin exercise to establish a local code of practice ensuring repeatability and consistency to generate high-quality accurate data for life prediction. The work has focused on crack length measurements, heating methods and temperature measurement techniques as well as pre-cracking procedures, the use of different specimen geometries and Digital Image Correlation imaging for crack monitoring. The majority of the tests have been carried out on a coarse grain polycrystalline nickel-base super alloy using two types of phase angles, namely Out-of-Phase and In-Phase TMF cycles with triangular waveform.
