EBSD and Subtle Crystallographic Differences - A Study of Resolving Interlayer Spacings in Nb-Ni and Nb-Co mu-phases

Lukas Berners, Nisa Ulumuddin, Annika Baum +9

In ordered intermetallics, slight variations in lattice site occupancy and specific interlayer spacings have been identified as the sources of significant changes in critical resol…

Origins of limited non-basal plasticity in the μ-phase at room temperature

W. Luo, C. Gasper, S. Zhang +7

We unveil a new non-basal slip mechanism in the μ-phase at room temperature using nanomechanical testing, transmission electron microscopy and atomistic simulation. The (1-105) pla…
