| Abstract Scope |
The decomposition kinetics are strongly influenced by the prior austenite grain size, thereby affecting the mechanical properties of the material. The austenite grain size is essential to understand the microstructure decomposition during the material's processing. The effect of precipitation has been widely studied in previous works, being critical microalloying element additions such as niobium and titanium. The present works describe the effect of the austenite grain size on resulting microstructures at a cooling rate of 50°C/s. Additionally, tensile and impact tests were performed to evaluate the resulting mechanical strength; with toughness assessed at 20°C, 0°C, and -50°C. The evolution of microstructure was studied using optical microscopy and SEM. |
