Inelastic properties evolution of alloy steels in martensitic and cold-worked states subjected to heat treatments up to 600/sup 0/C

Technical Report:

Abstract

Two internal friction peaks were observed in a ball-bearing steel in the martensitic and cold-worked states, near 220 and 280/sup 0/C for a frequency of about 1,3 Hz. From peaks evolution by annealing up to 600/sup 0/C, it is possible to follow the decomposition stages of martensitic and recrystallization of cold-worked pearlite. Annealed martensite and cold worked pearlite have the same anelastic behaviour. From existing atomistic models, it is possible to interpret these peaks by dislocations-interstitial carbon and dislocations-carbides interactions.
