| Abstract Scope |
Nanostructured bainitic steels have a superior combination of wear, strength, and toughness imparted by nanoscale dual-phase (ferrite/austenite) features. Combination of these excellent mechanical properties makes them ideal candidates for high wear service conditions. However, these classes of steels are still not widely used due to several processing challenges, including the long heat treatment (days) to form the nanostructure, and precise temperature and cooling rate control requirement from the high carbon content in these steels. To address these challenges, firstly, we have used novel alloy discovery techniques to accelerate the phase transformation kinetics. Secondly, we have adopted powder metallurgy/hot isostatic pressing (PM/HIP) route that offers the ability to control cooling rates, and the potential to fabricate large-scale near net shape parts and scaling up manufacturing. This talk will discuss the alloy design strategy, phase transformations, microstructural changes, and mechanical properties of PM/HIP processed novel nanostructured bainitic steel. |
