文摘

High-phosphorus steels are important for structural applications where corrosion resistance is required and are subjected to hot deformation processing. Therefore, hot deformation behavior of Fe-0.05C-0.13P steel is studied by conducting hot compression tests in the temperature range 750-1050 °C after austenitization at 1050 °C for 10 s. The strain rates ranged from 0.001 to 10 s−1. Optical and scanning electron microscopy was performed to determine the microstructural evolution. EBSD measurement on selected samples was used to determine the microstructural changes in the ferrite phase. Processing windows were determined using modified dynamic material model in order to determine the safe hot working domains and these are correlated with the microstructural developments.
