SAE 8620 - PSPP Map
This videos looks at the Processing-Structure-Property-Performance (PSPP) Map for SAE 8620 alloy steel, with an emphasis on its current industrial use cases which have driven research in applications such as tapered roller bearings. This PSPP map allows researchers and material scientists to better understand the processes that drive the microstructures, material properties, and ultimate performance. The PSPP map includes the process that are used to create the material, the microstructures that are a result of these process, the material properties that are driven by the microstructures, and finally the performance of the material in a real-world application. This map is created through the compilation of a thorough literature review that examines the mechanisms for particular applications, along with research into different heat treatment processes to get desired material properties.
