Discussion Overview

The discussion centers on the relationship between the elastic modulus (e-modulus) of materials and their melting temperatures. Participants explore whether this relationship is direct or inverse and consider specific materials in their analysis.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions the nature of the relationship between e-modulus and melting temperature, asking whether a direct or inverse correlation is expected.
  • Another participant suggests using a specific website to investigate the correlation across different materials, indicating that empirical data may be useful.
  • Some participants propose that there is a direct relationship between e-modulus and melting temperature, while acknowledging that there may be exceptions.
  • There is a mention of specific materials, such as calcium and iron, with a focus on their deformability at room temperature.

Areas of Agreement / Disagreement

Participants express differing views on the nature of the relationship between e-modulus and melting temperature, with some proposing a direct relationship while others suggest that exceptions may exist. The discussion remains unresolved regarding the specifics of this relationship.

Contextual Notes

Participants reference empirical data from specific materials without resolving the underlying assumptions or definitions related to the elastic modulus and melting temperature.

what is the relationship between e-modulus and melting temp?
 
Engineering news on Phys.org
What do you think ? Do you expect a direct or inverse correlation ? Have you tried searching to see if there is a correlation ?

Try this site : www.matweb.com and use the search option, with different materials. eg : oxygen free copper, 304 stainless steel, alumina, red brass, lead.
 
I think I got it--they have a direct relationship. Now I need to find out if Ca or Fe is more deformable at room temp...

...in general. There will be a few exceptions, but not for the pair you need.

In the matweb seach box type in "Calcium, Ca" and "Standard gray iron" to get their elastic modulii.
