Abstract
The purpose of this work is to study the effect of cold work and heat treatment ••the microstructure and mechanical properties of low and medium C-steel.
To carry out this study, two different approaches were used. The first approach is based on an experimental work and the second one is based on a computer simuiation. which was developed for this purpose.
Low and medium C-steel drawn wire samples of different cold work were d to two different types of heat treatment: HT1 is of slow cooling rate and Z or rapid cooling rate. Both the as-received and heat treated samples were {•nDteaea to microstructural analysis and mechanical tests. In the computer simulation JUTS and VHN were evaluated at different %cold work and different heat treatment
i.
fieeiines for both alloys.
The main findings obtained from the experimental work were:
As residual stresses increase, as a result of increasing %deformation .average diameter (D) decreases while the No. of grains per square inch (No./in ”) and index (G) increase in the cross-sectional direction. The reverse is true in the idinal drawing direction.
Increasing residual stresses also leads to an increase in both ultimate tensile Kth (”UTS) and hardness (VHN), with a subsequent decrease in ductility (%5) for i alloys
Application of slow cooling rate during the heat treatment HT1.
