Description

The HT650 furnace is designed to perform impulse excitation measurements at elevated temperatures up to 650 °C in an air atmosphere or with an inert gasflow (optionally). Measurements can be performed in predefined intervals during heating and cooling (1-5 °C/min) in order to determine the elastic properties and damping as function of the temperature. The measurement system can be upgraded to a maximum working temperature of 1050 °C.

Measurement examples

  • High-carbon steel C68

    High-carbon steels are used for applications in which high strength, hardness and wear resistance are necessary. In this case, the high-carbon steel C68 shows a monotonic decrease in Young's modulus with increasing temperature between room temperature and 600°C. The Young's modulus decreases from 216.46 GPa at room temperature to 125.9 GPa at 800°C. After 700°C, a phase transition can explain the variable decrease of the Young's modulus. The reliability and accuracy of material data leads to clear advantages in structural design calculations and modelling, for example, finite element analysis of stresses in high temperature plant components.
  • Aluminum sample

    IET measurements are performed in predefined intervals during heating and cooling (1-5 °C/min) in order to determine the elastic properties as function of the temperature. In this case, the Young's modulus and shear modulus of an aluminum sample are determined up to 260°C.
