When the temperature increases, the atomic thermal vibrations increase, and this will cause the changes of lattice potential energy and curvature of the potential energy curve, so the Young’s modulus will also change. And with the increase of temperature, the material will have a **volume expansion.Author: **Weiguo Li, Ruzhuan Wang, Dingyu Li, Daining Fang**Cited by: **32**Publish Year: **2011

## When does the Young's modulus decrease?As the temperature increases, the Young's modulus decreases almost linearly up to the quartz transition at 573 °C. Then the Young's modulus strongly increases up to the test temperature (700 °C). The decrease of the Young's modulus as the temperature increases was expected at least if no phase transformation, i.e., no structural changes occur.See all results for this question

### Why does the Young's modulus change?

When the temperature increases, the atomic thermal vibrations increase, and this will cause the changes of lattice potential energy and curvature of the potential energy curve, so the Youngs modulus will also change. And with the increase of temperature, the material will have a volume expansion.See all results for this questionWhen the temperature increases, the atomic thermal vibrations increase, and this will cause the changes of lattice potential energy and curvature of the potential energy curve, so the Youngs modulus will also change.

The study of effect of temperature on Youngs modulus is extremely important for the strength under high temperature and thermal shock properties of ceramics and refractories. When the temperature increases, the atomic thermal vibrations increase, and this will cause the changes of lattice potential energy and curvature of the potential energy curve, so the Youngs modulus will also change. And with the increase of temperature, the material will have a volume expansion.
