Elevated temperature tensile test
A hot tensile test is performed at elevated temperatures to determine the temperature-dependent strength values of metals. It provides important data for high-temperature structures.
Physicochemical mechanism of action
A hot tensile test involves pulling a specimen at elevated temperature. This allows measuring stress and strain as a function of temperature, providing temperature-dependent strength values.
Metallurgical relevance & risks during welding
The results of the hot tensile test help in selecting suitable materials for high-temperature applications. Incorrect material selection or insufficient knowledge of temperature-dependent properties can lead to cracks, failure, or reduced service life.
Workshop practice & instructions
For the hot tensile test, a specimen is pulled at a specific temperature. Stress and strain are measured and recorded. It is important to use the correct temperature and material to achieve accurate results.
