| Abstract Scope |
Catastrophic heat of fire on steel causes the temperature to rise rapidly due to high thermal conductivity of steel and forms carbide at 650°C. To prevent this, a few steel grades were developed having higher yield strengths at elevated temperatures. This work presents the assessment of presence of different phases; Physical and Mechanical properties at certain temperature and time by adding different composition of Mo (0-0.75% with 0.25% in succession) on EN 10025-2:2004 Grade S355 at elevated temperature using CALPHAD based computational technique. Optimized amount of molybdenum with other alloying elements can intelligently manipulate microstructure to improve strength. It may give some observation about the improvement of common structural steels upon addition of Mo. Besides high temperature strength in addition to Mo on steels, it also provides creep resistance and corrosion resistance. The overall predictions provide observations about the improvement of common structural steels with addition of Molybdenum. |
