| Abstract Scope |
High-silicon stainless steel, abbreviated as ‘Silicolloy’, has earned importance owing to their excellent set of properties. In this study, effect of Si content (up to 6 wt%) on the microstructure and mechanical properties of 15kh18N12C4TЮ (yu) silicon steel has been studied. Microstructural characterization was performed by using a combination of SEM, EDS and EBSD. Increasing the Si content led to change in the microstructure from ~100% austenite (γ) to 66% ferrite (α) + 34% austenite (γ). Further, SEM and EDS results confirmed the presence of (Ti,V) carbo nitride precipitates in all grades of FeSi alloy. The EBSD and nano-indentation were conducted to establish the correlation between nano-mechanical properties, such as hardness (H)/modulus (E) and orientation of grains along with the determination of mechanical properties of the individual phases. Uniaxial tensile testing and fractography were carried out to quantify the flow behavior and understand the deformation mechanism and will be discussed. |
