| Abstract Scope |
In this work, a compositionally graded Ti-(Ti-20wt.%Fe) alloy was built, using laser-directed energy deposition (L-DED), to achieve a continuous variation in microstructure and mechanical properties. By optimizing printing parameters, low porosity compositionally graded Ti-Ti20Fe builds with steps of five distinct compositions have been deposited. The pure Ti side with 100% HCP α transforms to 100% BCC β towards Ti20Fe side, with evolving phase fractions and refining α phase in between. This build transitions from a ductile, corrosion resistant pure Ti to strong, wear resistant Ti-20Fe end, with systematic changes in elastic modulus and micro-hardness. The effect of various heat treatments on this alloy was also investigated. This cost-effective graded alloy, offering both toughness and strength, could potentially be used in energy, aerospace, and marine applications. |
