| Abstract Scope |
To enhance the solar absorptivity of Inconel-type alloys without using absorptive coatings that degrade at high temperatures above 700 °C, Powder Bed Fusion (PBF) was utilized to create alloys in-situ by introducing trace elements such as boron or tungsten. Both elements have high absorptivity; however, it is important to avoid compromising the physical properties of the alloy. Material design has been investigated through computational resources and software such as Density Functional Theory (DFT) and Molecular Dynamics (MD); this methodology was adopted to explore the potential material properties of structures produced by introducing these elements. The proposed alloy mixtures were then created via both V-mixer and mechanical alloying in a particle ball mixer. Each powder set was used in PBF manufacturing to produce samples that verify the results of the computational study. Furthermore, the laser parameters were studied to examine their effects on the new material mixture. |
