“…Considering this, the introduction of inoculating agents during the WAAM process can promote the grain refinement and modify the existing phases. Typical inoculation agents for low alloyed steels are the rare earth metal oxides, NbC-containing ferroalloy, or TiN-containing ferro alloy [14,15]. One potential inoculant agent for low alloyed steel is SiC particles due to their properties such as high hardness and high melting point [11], opening possibilities for use of carburized kerf residue.…”

Silicon kerf residue is generated during the wafering process of pure silicon in the photovoltaic value chain. The generated by-product has a high volume, and the particle size is typically below 1 µm. Although the fine particles are partly oxidized, the material may be beneficial in different metallurgical applications such as grain refining and alloy composition adjustments. This work studies the dissolution behavior of silicon kerf in low alloy steel melts with the aim to upcycle the kerf material in the steel industry for different purposes. In this study, a steel alloy and the kerf residue were melted (at 1580 °C) in an alumina crucible placed in an induction furnace. The amount of added kerf residue was varied. The behavior of the particles in the solidified alloy was characterized by using an optical microscope, electron probe microscope (EPMA), and wavelength-dispersive X-ray spectroscopy (WDS) in order to study the dissolution behavior of the Si-kerf residue in the steel.
