Low Cycle Fatigue Test, High Cycle Fatigue Test, and Creep Test
Universal Testing Machine inspekt table 10kN with High-Temperature Radiation Furnace
The Low Cycle Fatigue Test (LCF), High Cycle Fatigue Test (HCF), and Creep Test are crucial methods for evaluating the fatigue behavior and long-term durability of materials under thermal and mechanical stress conditions.
Test Setup and System:
The testing system consists of the inspekt table 10kN universal testing machine combined with a high-temperature radiation furnace and an EXA15-1.5 extensometer. This setup is specifically designed for LCF, HCF, and creep testing of specimens with a diameter of 1-4 mm at temperatures up to 1250°C. The furnace, a two-part radiation furnace from Xerion, can be flexibly mounted at the bottom and back, allowing precise heating of the specimens.
Application Area:
This testing system is used to evaluate the mechanical properties of turbine components made from high-performance materials. It focuses on flat specimens, both with and without holes, to investigate their fatigue behavior at high temperatures and varying cycle numbers.
Testing Methods:
- Low Cycle Fatigue Test (LCF): In this test, specimens are cyclically loaded to a specific stress level to assess material behavior under low cycle numbers but high stress levels. This provides essential insights into the material's lifespan under extreme operating conditions.
- High Cycle Fatigue Test (HCF): In the HCF test, specimens are subjected to high cycle numbers but lower stress levels. This method is particularly suitable for examining the fatigue behavior of materials in applications involving many load cycles, such as in turbines.
- Creep Test: During the creep test, the material is tested over an extended period under constant load and high temperatures. This is used to determine the creep resistance and strain changes over time, which is especially crucial for turbine materials that must remain stable over long operating periods.
Control and Data Acquisition:
The universal LabMaster testing software controls the entire testing process, capturing and analyzing the measurement data in real time. It provides extensive evaluation and reporting capabilities that are essential for the precise analysis of test results.
This system enables comprehensive and accurate testing of high-performance materials under extreme conditions, providing valuable insights for the development and optimization of turbine components.
