Finer TiB 2 powders having better microwave absorptivity may be used to facilitate relevant reactions with less addition.…”

The selective laser melting (SLM), also termed as laser powder bed fusion (LPBF), is attractive for its ability to fabricate complex metallic components with great geometrical design freedom and manufacturing capacity. [1,2] The high heating/cooling rate and thermal input of laser processing result in refined grain and tailored microstructure, [3] leading to a notable Hall-Petch effect and improved mechanical performance of manufactured parts. Furthermore, SLM provides an effective way for the design and fabrication of high performance metal matrix composites (MMCs), wherein varieties of reinforced particles, [4,5] carbon nanotube, [6] and whiskers [7] can be added to metals, alloys, and even intermetallics through both ex situ and in situ approaches. [8] High speed steels (HSS) [9] are widely used in the production of cutting tools, drilling tools, extrusion molds, precision dies, and high temperature bearings due to their combination of high hardness (>60 HRC), strength (bending strength >2000 MPa), and wear resistance (high amount of carbides). In recent years, SLM of high speed steel, cold work die steel, hot work die steel, and similar tool and die steels has gained significant attention due to its ability to produce complicated parts and implementation of individually forming internal cooling channels. [10,11] This can significantly increase the cooling efficiency, application reliability, and service life of SLM-manufactured tools and molds. However, the available data in the literature [12,13] have shown that high speed steels are prone to cracking during the SLM cyclic remelting process with fast cooling rates due to their high carbon content (ranging from 0.8 to >3 wt%), [14] large amount of strong carbide forming elements, and thermal residual stress. The microstructure of SLM-processed high speed steel usually consists of martensite, retained austenite, carbides, and possibly eutectic structures. [15] In addition, Saewe et al. [16] found that the temperature gradients in the SLM process create grain growth in the build direction, resulting in columnar dendritic crystal, which can cause brittleness and promote crack formation. Recent results produced by Platl et al. [17] suggest the cracks propagate predominantly along the network of M 2 C eutectic carbide deposited at the grain boundaries of carbon martensite and retained austenite matrix. They indicated that the stress-induced cracking of eutectic carbides, which emerge from the tensile stress accumulations during solidification and cooling stages, is the predominant cracking mechanism of the LPBF-processed tool steel. Therefore, several studies focus on the additional preheating [18,19] during the SLM process to reduce the cumulative tensile stress and residual stresses. Among these studies,
