plot the Youngs modulus at room temperature vs the materials

plot the Young’s modulus at room temperature vs. the materials thermal expansion. Discuss possible reasons for trend, if any. [Please explain]

Solution

There is no trend between Youngs Modulus and Thermal Expansion Coeff directly Thermal Expansion Coefficient is higher for Alloys than pure metals for the same Youngs Modulus Thermal Expansion is mostly depend material structure Thermal Expansion Coefficient for Ceramics is low though their Youngs Modulus is relatively high than metals and Alloys On the other hand Polymers have highest Thermal Expansion Coefficients for relatively very low Youngs Modulus
