Cast iron specific heat in function of the temp

Click For Summary
SUMMARY

The discussion focuses on the relationship between the specific heat of cast iron and temperature, particularly for thermal analysis of disc brakes. Participants highlight that ductile iron, a type of cast iron, has a high carbon content, which is crucial for understanding its thermal properties. A referenced resource provides specific heat data, suggesting that average values should be calculated from given temperature ranges, such as assuming 110°C for the range of 20-200°C and 160°C for 20-300°C. This information is essential for accurate thermal analysis in engineering applications.

PREREQUISITES
  • Understanding of specific heat and its significance in thermal analysis
  • Familiarity with materials science concepts, particularly regarding cast iron and ductile iron
  • Basic knowledge of temperature ranges and averaging techniques
  • Access to relevant materials science resources or databases
NEXT STEPS
  • Research the specific heat values of ductile iron at various temperatures
  • Explore materials science literature on the thermal properties of cast iron
  • Learn about thermal analysis techniques for disc brakes
  • Investigate the impact of carbon content on the thermal properties of cast iron
USEFUL FOR

Engineers, materials scientists, and automotive professionals involved in thermal analysis and design of disc brake systems will benefit from this discussion.

Hi all,

I need the relationship between cast iron specific heat and temperature in order to perform a disc brake thermal analysis. Where could I get this data? I just need average values for a typical cast iron used for disc brakes.
Any suggestion is appreciated

Thanks

Scroll down to the part that says specific heat. Apparently, ductile iron is a type of cast iron. I've never liked the term cast iron very much, as it's a little confusing just what one means when they use the term. As I remember from materials science, cast iron has a high carbon content, higher than what steel generally contains.

Anyway, http://www.ductile.org/didata/Section3/3part2.htmseems to be referring to cast iron as a high carbon alloy.

Or copy and paste link if you desire: http://www.ductile.org/didata/Section3/3part2.htm

Note: since it gives a range, I would find the average of the range and assume that as the temperature. For instance, 20-200 C would assume 110 C. 20-300 C would assume 160 C.

Hi jlefevre76,

thanks for your reply, you provide me what I need.

cheers
