Author(s): Evie Ladbrook, Jon P. Wright, and Mark S. Senn Structural phase transitions generate complex microstructures that often govern material functionality, yet directly resolving their three-dimensional organization in bulk samples remains challenging. Here we employ scanning three-dimensional x-ray diffraction (3DXRD) to resolve the bulk microstruct… [Phys. Rev. Lett. 137, 126504] Published Thu Sep 17, 2026
