The abrasion resistance of the Ti-5Al-4Zr-4Mo-2Cr-2Sn-1Fe alloy was investigated using multi-pass dual-indenter (MPDI) scratch tests with different loading conditions under a repetitive local sliding contact. Various microstructures were obtained with different heat treatments. The effect of the phase morphology on the scratch resistance and corresponding failure mechanisms were revealed. Results show that the phase morphology has a great influence on the scratch resistance and that the effect is contact-load dependent. The scratch behaviour is linked to the initial surface hardness at low loading conditions, while the work-hardening ability is more relevant at high loading conditions.
