Abstract
Workability of two compositions (Fe-11wt% Al with 0.5wt% C and 1.1wt% C) was investigated using Stain Induced Crack Opening (SICO) test in a Gleeble 3800 thermomechanical simulator. SICO tests were conducted in the temperature range of 1073K to 1373K at strain rates of 0.05 to 0.1s-1. Both the alloys exhibited good workability with no tendency for cracking. However, refinement of microstructure due to thermomechanical processing could only be observed at 1373K for both the alloys. At lower temperatures slightly aligned and elongated structure was observed. Stress required for deformation increased with decrease in temperature and increase in strain rate. Stress values increased with increase in carbon content. Hoop strain was found to increase with test temperature and increase with carbon content. These results are related with observed microstructure.
