Optimization of the Inter-Operation Annealing of Cold-Drawn Eutectoid Steels

Abstract

The test of the results presented in this paper has demonstrated that the most suitable recrystallizing annealing temperature for cold drawn eutectoid steels is 700• C. The microscopic examinations, with the use of scanning electron microscopy and transmission electron microscopy and the results of mechanical properties tests have shown that only at this temperature it is possible to obtain the fully recrystallized homogeneous fine-grained structure of the pearlitic steel.
