Exploring the Merit of Non-Destructive nf-HEDM in Characterizing Textured Materials

In his presentation at the 8th International Symposium on Superalloy 718 and Derivatives on Wednesday, October 1, 2014 at the 10:00 AM in the Marquis Ballroom of the Marriott City Center in Pittsburgh, PA, Dr. Chris Hefferan will describe an OIM technology, near-field High Energy X-ray Diffraction Microscopy (nf-HEDM), that enables a new way of interpreting microstructural data in textured materials.

The Population of Twin-Related Boundaries in High Purity Nickel as Measured with Near-Field High Energy X-ray Diffraction Microscopy

Understanding of both how materials are assembled and what governs their behavior while they are in service has always been a fundamental mission for materials scientists. Thus, the body of analytical instrumentation available for materials characterization is constantly growing. Included in these innovative characterization technologies is orientation imaging microscopy (OIM)—a tool that enables a new way of interpreting microstructural data in textured materials. Using the non-destructive, synchrotron-based OIM technique known as near-field high energy x-ray diffraction microscopy (nf-HEDM), we mapped a volume of nickel microstructure after it had been subjected to multiple anneals. The material response is quantified, with focused attention on the properties of the grain boundary network. Specifically, we interpreted the populations of boundaries that can be described with a Σ3n misorientation. The results exhibit sensitivity to a unique physical signal that had not been observed in previous OIM measurements and demonstrate the merit of non-destructive nf-HEDM in characterizing textured materials.

8th International Symposium on Superalloy 718 and Derivatives

The conference, sponsored by the TMS High Temperature Alloy Committee of the Structural Materials Division and by ASM International, will be held September 28-October 1, 2014, Marriott City Center, Pittsburgh, PA. It covers all aspects of metallurgical processing, materials behavior and microstructural performance for a distinct class of 718 type superalloys and derivatives. The technical presentations will focus on alloy and process development, production, product applications, trends and the development of advanced modeling tools.

We hope to see you at the conference!
