| Abstract Scope |
This study is concerned with Ferritic-Bainitic steel of chemical composition of 0.2 wt% C, 0.5wt% Si, 1.2wt% Mn. The metallic casted block was cut then, hot rolled and heat treated at 3 different heat treatment programs. Heat treatment program applied was heating up sample to 850℃ , 900℃ and 950℃ then quenching it in a salt bath for 30 minutes to (450℃ – 500℃ – 550℃) .The sample was shaped to apply metallurgical test. The best results were shown for tensile and yield strength took place when samples are heated to 850℃ and then quenched to 450℃ , while the best results reached for toughness when samples are heated to 850℃ and then quenched to 550℃ . However elongation percentages are almost the same during all heat treatment programs. Microstructure investigation also showed a reduction in grain size after heat treatment applied compare to hot rolled samples only. |
