Abstract

The mechanical properties of hot-and cold-rolled steels under various manufacturing conditions have been the subject of several investigations. Fracture toughness, an important design factor for the selection of materials and appropriate design stress levels for fractur resistant structures, did not take much attention in this repect. 
in this paper, the effect of the temperature at the final steel manufacturing process coiling temperature, on the plane stress fracture toughness for 0.1% carbon rolled step was investigated. Other aspects such as specimen rolling direction and thickness of strip have been considered. 
Owing lo practical reasons, the normal operating coiling temperature is set at 710°C
 For the purpose of this study, the conditions at the coilers have been controlled to bring the coiling temperature down to 630°C. 
Test results indicated that the plane stress fracture toughness for the test material has improved by about 17% when the roiling temperature was brought down from 710°C 630"С. Microstructural examination indicated that the grain size or the material decreased with decreasing the coiling temperature. This is known to be responsible for reducing the tendency to nucleate cracks at the grain boundaries leading to increasing the material's resistance to fracture.
