Abstract (englisch):

BCC Mo-Ti solid solutions were synthesised by arc-melting in the range of 0-80at% Ti. Mechanical properties were scale-bridging characterised using nanoindentation, Vickers hardness testing and compression testing to isolate solid solution strengthening. Additional structural (XRD) and compositional analyses (HCGE) were also performed to assess lattice parameter and synthesis-related uptake of O and N. In order to assess strength contributions by screw and edge dislocation motion, the model-compatible descriptions of edge dislocation-controlled solid solution strengthening (Maresca and Curtin, Acta Materialia 182 (2020) 235-249) and screw dislocation controlled strengthening (Ghafarollahi and Curtin, Acta Materialia 226 (2022), 117617) were implemented and the strength of the solid solutions was modelled.

Three ASCII-files are included:
Mechanical properties (nanohardness, Vickers hardness, offset yield strength and Young's modulus) are found in mech_properties.txt. Lattice parameter data, O and N contents and Ti contents determined by EDX are found in other_properties.txt. All mechanical properties are given with their standard deviation. Strength modelled by the implementations of solid solution strengthening are found in Curtin_models.txt for both dislocation types.
