How is it possible for Invar to have such a low temperature expansion coefficients (0.9) when it is made up of iron (12) and nickel (13) which both have s significantly higher temperature expansion coefficients than the final product itself (being Invar)?

as two metals are been mixed it results in an alloy...it depends on the arrangement of atoms in the alloy and its physical properties.......these properties of alloy made a revolution in the world......its amazing right???i will let you know if i get more info abt these......

anonymous · Answer

and ya temperature expansion coefficients are intrinsic propety of a substance...

Pretty amazing.  Thank you.

Yes the molucules (atom) arrangement change the internal energy, (vibrational energy of and transfer between the molecules)

Interesting...  Does that mean that it is possible to take a specific material and change the  temperature expansion coefficient withought adding another material to it (making it an alloy) by simply rearranging the molucules (eg exposure to high vibration)?
