“…The blocky particles are a primary TiC formed at high temperature and have an isotropic polygonal shape. These particles are distinguished from secondary TiC particles with needle-like or plate-like shape located at the grain boundary [32]. Blocky particles are distinctly distributed in EEMMC1.5-T. EEMMC1.5-C had several dendritic particles with short secondary arms, and EEMMC1.5-B consisted of blocky particles and dendritic particles where secondary arms were highly developed.…”

TiC-reinforced metal matrix composites were fabricated by laser cladding and FeCrCoNiAlTiC high entropy alloy powder. The heat of the laser formed a TiC phase, which was consistent with the thermodynamic calculation, and produced a coating layer without interfacial defects. TiC reinforcing particles exhibited various morphologies, such as spherical, blocky, and dendritic particles, depending on the heat input and coating depth. A dendritic morphology is observed in the lower part of the coating layer near the AISI 304 substrate, where heat is rapidly transferred. Low heat input leads to an inhomogeneous microstructure and coating depth due to the poor fluidity of molten pool. On the other hand, high heat input dissolved reinforcing particles by dilution with the substrate. The coating layer under the effective heat input of 50 J/mm2 had relatively homogeneous blocky particles of several micrometers in size. The micro-hardness value of the coating layer is over 900 HV, and the nano-hardness of the reinforcing particles and the matrix were 17 GPa and 10 GPa, respectively.

“…Notably, a substantial shift of the in situ reinforcements to the nanometer (nm) size range for the investigated chemical compositions is possible through the utilization of rapid cooling processes, such as gas atomization and additive manufacturing. In the authors' recent investigations, [25,26] this approach has been successfully employed to fabricate Fe-5TiC composites, resulting in significantly finer reinforcement particles and, consequently, improved mechanical properties of the MMC.…”

Fe–xTiC in situ metal matrix composites (MMCs) are fabricated utilizing a cold crucible inductive melting (CCIM) technique with varying TiC amounts (2, 3.5, and 5 wt%). Steel blocks and pure Ti plates are remelted in a water‐cooled cupper crucible. The subsequent solidification of [Ti]‐ and [C]‐rich melt yields TiC reinforcement particles in an ingot. The holding time varies between 5 and 30 min, whereas the holding temperature alters depending on the amount of TiC, ranging from 1380 to 1620 °C for Fe‐5TiC and Fe‐2TiC, respectively. Alloying efficiency for TiC‐forming elements is estimated for all fabricated Fe–xTiC ingots by comparing [Ti] and [C] target values with measured ones. The lower TiC amounts and shorter holding times result in decreased [Ti] and [C] losses. SEM analysis of three cross‐section samples representing different TiC amounts reveals two distinct morphologies of TiC in situ reinforcements: primary blocky/cubic and eutectic plate‐like precipitates. The blocky precipitates appear slightly finer with a decrease in TiC amount (4.4 ± 1.2 μm for Fe‐5TiC and 3.8 ± 0.7 μm for Fe‐2TiC), whereas the length of plate‐like precipitates noticeably decreases in the samples with lower TiC amounts (11.0 ± 7.0 μm for Fe‐5TiC and 6.8 ± 3.6 μm for Fe‐2TiC).

“…[113,114] Pre-alloyed powder containing Ti and B has also been successfully used to form TiB 2 reinforcement in an Al matrix. [110,115] These studies focused on LPBF fabrication; however, the trends are likely to be transferable to LDED [116][117][118][119] and EPBF [120][121][122] fabrication due to the mechanisms behind the elevated-temperature mechanical properties increase, as described in detail later in Section 3.3. Although their high-temperature mechanical properties have not yet been evaluated, other CDAs have also been successfully additively manufactured.…”

Many industries such as aerospace, power generation, and ground transportation demand structural materials with high specific strength at elevated temperatures. Up until now, many types of heat‐resistant materials including Ni‐based superalloys, intermetallic compounds, and dispersion‐strengthened alloys have been developed for specific applications in these industries. Moreover, with the recent development of additive manufacturing techniques, these industries can now benefit from the rapid prototyping abilities, geometric freedom, and increased mechanical properties that can be achieved through various additive manufacturing processes. With this in mind, the progress made in additive manufacturing of heat‐resistant intermetallic compounds and ceramic dispersion alloys is herein examined. A brief introduction is provided on the target industries, applications, and the compositions of heat‐resistant alloys of current research interest. Then, recent research on heat‐resistant intermetallic compounds and ceramic dispersion alloys fabricated by additive manufacturing processes such as laser powder bed fusion, laser direct energy deposition, and electron‐beam powder bed fusion are reviewed with information provided on microstructure, processing parameters, strengthening mechanisms, and mechanical properties. Finally, an outlook is provided with future research suggestions.
