Influence of local tensile direction on martensitic variant selection in the superelastic Ti-20Zr-12Nb-2Sn alloy

Key Points

• Martensitic variant selection is significantly influenced by local tensile direction in the alloy.
• The analysis reveals that varying the tensile direction alters the material's microstructure during phase transformation.
• Experimental observations across multiple orientations confirm the role of local tensile stress in superelasticity.
• Understanding this influence may enable improved designs for biomedical and engineering applications of this alloy.
