Grain Boundary Migration: A Disconnection Perspective

April 27 @ 11:00 am - 12:00 pm
EB1 – Room 1011, 911 Partners Way
Raleigh, NC 27695-7907 United States

Abstract: This talk addresses how grain boundaries (GBs) migrate under a range of different driving forces. Our approach is based on a description of the motion of crystallographic line defects in GB,; i.e., disconnections. First, I will review the relationship between disconnections and the underlying bicrystallography; this relationship determines the set of all allowed Burgers vector and step heights (geometric properties of disconnections) for each GB {b,h}. Next, I will show how GBs move under no driving force and for…
