Damage Mechanics Model Development for Monocrystalline Superalloys (PREPRINT)

Abstract

This research in support of the Air Force Research Laboratory Materials and Manufacturing Directorate was conducted at Wright-Patterson AFB, Ohio from 1 August 2007 through 15 October 2009. The objective of this task was to develop methods to better predict damage initiation, such as cracking, in superalloys under engine representative conditions. This report details work that focuses on characterizing the material microstructure of single crystal nickel-based superalloys, which is important for damage initiation in these materials. Additionally, this report details work that involves in situ mechanical testing of miniature specimens within the SEM as well as the setup of a miniature test specimen apparatus.
