About this Abstract
Meeting 2017 TMS Annual Meeting & Exhibition
Symposium Pan American Materials Congress: Nanocrystalline and Ultra-fine Grain Materials and Bulk Metallic Glasses
Presentation Title Fatigue Behavior of Friction Stir Processed Ultrafine Grained 5024 Al Alloy
Author(s) Shivakant Shukla, Mageshwari Komarasamy, Rajiv Mishra
On-Site Speaker (Planned) Shivakant Shukla
Abstract Scope Ultrafine-grained (UFG) microstructure in 5024Al alloy was produced via friction stir processing. The fatigue properties were investigated using fully reversible bending fatigue testing machine. Microstructural evolution during fatigue tests were analyzed by doing interrupted fatigue tests and subsequent orientation imaging microscopy (OIM) of the sample. In order to investigate the effect of grain size on the fatigue micro-mechanisms, three different grain sizes comprising of two UFG, and a coarse-grain materials were chosen. Particular emphasis was given to the role of grain size on the evolution of deformed structure and intergranular dislocation density. OIM was used to understand the preferable crack nucleation site based on Schmid Factor, dislocation density, and grain boundary character distribution. The fractured samples were inspected using scanning and transmission electron microscopes to understand the failure mechanism in UFG material.
