AIST Webinar 1:30 PM ET -3:00 PM ET

Attendees will learn about a variety of metallurgy, processing, products and applications-related topics that were originally scheduled for presentation at AISTech 2020. This webinar will present three papers including "Generation of High-Corrosion-Resistance Surface-Optimized Diffusion Alloy (SODA) Steel Sheet for Forming Operations," "Development of Nanobainitic Steels With Accelerated Kinetics and Tensile Strength of 1.7-2.0 GPa" and "A Modified Johnson-Cook Model Incorporating the Effect of Grain Size on Flow Stress."

Generation of High-Corrosion-Resistance Surface-Optimized Diffusion Alloy (SODA) Steel Sheet for Forming Operations

Zack Detweilers, Arcanum Alloys

Arcanum Alloys has developed a method to generate variable chromium concentrations at the surface of a steel substrate at the sheet coil scale. This presentation will cover the development of a steel substrate that is compatible with high-temperature annealing and diffusion alloying. The corrosion performance of the resulting alloy will also be discussed in terms of surface chromium concentration and steel substrate chemistry. Lastly, the mechanical properties will be presented to highlight the potential of spatially segregating alloys with this platform technology.

Development of Nanobainitic Steels With Accelerated Kinetics and Tensile Strength of 1.7-2.0 GPa

Minal Shahr, CSIR-National Metallurgical Lab

Nanobainite steels with medium carbon ~0.5 wt.% are produced in the present work with faster kinetics and without the addition of cobalt and aluminum. Nanobainitic steel of 1.7-2.0 GPa ultimate tensile strength is used in application of wear resistance, ball bearing and gears. Kinetics of bainitic transformation was investigated by emphasizing on influence of alloying elements to produce nanobainitic steel. Reduction of carbon in the alloy accelerates the kinetics of transformation as it increases the driving force for bainitic transformation and it reduces activation energy of the dislocation barrier determined using a kinetic model. The activation energy of the dislocation barrier has a direct relation on austenite strength at the transformation temperature.

A Modified Johnson-Cook Model Incorporating the Effect of Grain Size on Flow Stress

Shouvik Ganguly, Missouri University of Science and Technology

The mechanical properties of steel are influenced by grain size, which can change through nucleation and growth at elevated temperatures. However, the classic Johnson-Cook model that is widely used in hot deformation simulations does not consider the effect of grain size. In this study, the Johnson-Cook model was modified to incorporate the effects of austenite grain size on flow stress. A finite element model was employed to characterize the effects of grain size on the flow stress for different steel grades over a range of temperatures (900°C to 1,200°C). Simulation results show good agreement with experimental observations.
