Abstract
Measurements performed when reheating recently quenched Fe-Ni-C structures from 77 to 300 K indicate that internal friction behaviour is greatly influenced by internal stresses. The effect of cold-working at 77 K is reported. The twinning induced in that case and the martensitic transformation twinning appear to have cumulative consequences on the internal friction plot. A comparative study is conducted on different structures in order to confirm these observations. The results lead us to suggest a new approach for the physical interpretation of the internal friction measurements on recently quenched Fe-Ni-C structures in the (77-300) K temperature range.
