Title: Improving the Mechanical Properties of Metallic Materials via Nano structuring

Time: 10:00 - 11:00 AM, Friday, June 2, 2017

Place: Conference Room 201, HPSTAR (Shanghai)

Host: Dr. Hongwei Sheng

Abstract

The mechanical properties of metallic materials can be significantly improved by nanostructuring. Bulk nanostructured metallic materials can be produced via grain refinement using severe plastic deformation (SPD). The stacking fault energy of materials is a key factor that determines the final structure and minimum grain size achievable by SPD processing. In this presentation, I will discuss how stacking fault energy affects the SPD-induced grain refinement process and how the minimum grain size is achieved. I will also discuss some atomic mechanisms of defect interactions in nanostructured materials that would contribute to the improved strength and ductility of the nanostructured materials.
