A Study Of Several Commercial Steels In The Red Short Range, Jorge Alberto Espana
Masters Theses
"The red short phenomenon present in steel, was studied by means of torsion tests at temperatures between 800 and 1200⁰C. Cold drawn bars of different compositions of steels were tested, and the number of turns to failure and maximum twisting torque were plotted versus temperature.
All the steels tested, exhibited to have a certain degree of red shortness. By comparing the curves and the respective chemical analyses, the detrimental effect of sulphur and lead and the beneficial effect of manganese, was established.
Microscopic examinations revealed the intergranular nature of the cracks in the red short range. Sulphur and oxide distribution …
