T-6Al-2Sn-4Zr-2Mo (Ti6242) is a near-α titanium alloy, suitable for high-temperature applications. Unlike the conventional α+β Ti-6Al-4V (Ti64), with applications below 400°C, Ti6242 can be readily used in high temperatures up to 540°C. Ti6242 has been conventionally manufactured through casting and forging techniques. The emergence of additive manufacturing (AM) processes as revolutionary manufacturing techniques makes it imperative to study the fabrication of Ti6242 through AM processes. In the current study, Ti6242 samples were fabricated through the laser powder bed fusion (L-PBF) process with different process parameters. The micromechanical properties (e.g., indentation hardness, plasticity index, wear index, reduced modulus) of the as-built and heat-treated L-PBF-Ti6242 were evaluated using a depth-sensing indentation testing technique. The results were compared to the L-PBF-Ti64 counterparts to draw a perspective on the effect of material composition on the micromechanical properties.
