Relation between Young's modulus and the coefficient of thermal expansion

Click For Summary
SUMMARY

The discussion centers on the relationship between Young's modulus, melting point, and the coefficient of thermal expansion (CTE). It is established that while a high Young's modulus often correlates with a higher melting point and a lower CTE, this relationship is not universally applicable across all materials. The correlation can be explored using Wolfram Alpha, particularly for chemical elements, where deviations from this trend can be observed.

PREREQUISITES
  • Understanding of Young's modulus and its significance in material science
  • Knowledge of the coefficient of thermal expansion (CTE) and its implications
  • Familiarity with melting point concepts in materials
  • Basic proficiency in using Wolfram Alpha for data analysis
NEXT STEPS
  • Investigate the correlation between Young's modulus and melting point in various materials
  • Explore the coefficient of thermal expansion in metals versus polymers
  • Learn how to use Wolfram Alpha for material property comparisons
  • Research exceptions to the general trends in material properties
USEFUL FOR

Material scientists, engineers, and researchers interested in the mechanical properties of materials and their thermal behaviors.

Is it true for all material that if young's modulus is high then melting point will be high and coeff of thermal expansion will be lower? Any example that doesn't follow the above statement.

Many Thanks

Please see the discussion of the correlation between stiffness, melting temperature, and thermal expansion here. You can investigate the correlation using Wolfram Alpha and verify that for the chemical elements, for example, the correlations exist but are not perfect.
