In-situ DFXM Study of Grain Boundary Migration in CuAlMn
Abstract
Grain boundary migration in real alloys is often governed by stored strain energy rather than curvature, yet direct experimental observations remain scarce. We propose a three-day in-situ dark field X-ray microscopy (DFXM) experiment at ID03 to investigate strain-energy-driven grain boundary migration and dislocation generation in the Cu71.6Al17Mn11.4 shape memory alloy. By focusing on isolated flat grain boundaries and single-grain reference samples, we eliminate curvature and network effects and directly probe the role of plastic strain.
