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 FangCited by: 32Publish 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

material science - Why doesn't the Young's modulus change how does young s modulus change in rise in temperature

When certain solid materials, pure metal, steel or an alloy of a certain composition, gets strengthened by cold working or by heat treating, the Young's modulus stays exactly the same as before even though the yield strength of that material gets doubled, and the elongation gets reduced by an order of magnitude. Take maraging steel 350 for example.how does the youngs modulus change with the rise in how does young s modulus change in rise in temperaturehow does the youngs modulus change with the rise in temperature - Physics - TopperLearning how does young s modulus change in rise in temperature | h2s29655Youngs modulus: Youngs modulus of Steels [With PDF how does young s modulus change in rise in temperatureFor a specific material, the value of Youngs modulus or the modulus of elasticity is constant at a specified temperature. But with a change in temperature the value of Youngs modulus changes. With an increase in the material temperature the modulus of elasticity of a material decreases.
