摘要

Ti-6Al-2Zr-1Mo-1V (TA15) with ultrafine crystallites and numerous nano-scale twins were successfully prepared by selective laser melting (SLM). The room-temperature and high-temperature (500 degrees C) tensile properties of SLM-fabricated samples were visibly higher than those of TA15 fabricated by conventional techniques, other near a titanium alloys and even comparable to TA15-based composites.
