Effect of annealing on point defect population in cold-drawn pearlitic steel wires

Cold-drawn pearlitic steel wires were subjected to differential scanning calorimetry and resistivity measurements during heating. Both techniques yield two peaks, one at 500–600K, the other at 400–450K. Whereas the peak at 500–600K can be ascribed to voids consisting of about 10 vacancies as confirm...

Description
Summary:Cold-drawn pearlitic steel wires were subjected to differential scanning calorimetry and resistivity measurements during heating. Both techniques yield two peaks, one at 500–600K, the other at 400–450K. Whereas the peak at 500–600K can be ascribed to voids consisting of about 10 vacancies as confirmed by positron annihilation spectroscopy, the low-temperature peak is ascribed to V1C2 and/or V2C4 complexes.
