“…It is now recognised that laser powder bed fusion (LPBF) may offer a pathway to overcome this limitation and achieve complex MMC components by near net-shaping [4,5]. Promising research regarding Ti-based MMC fabricability via LPBF has been performed but development in this area has been limited by powder feedstock quality and supply [4,[6][7][8][9][10][11][12][13][14][15][16]. Numerous authors have demonstrated enhanced mechanical properties of Ti and Ti6Al4V reinforced by TiC/TiB through LPBF utilising gas-liquid reaction [11], powder mixing [6,13] or mechanically alloyed powder [8,10,17,18].…”

Ti-based metal matrix composites (MMCs) represent a material class with highly desired performance for the aerospace industry, but implementation has been hindered by poor processability. It is now being realised that MMCs can be formed in situ through the exploitation of rapid cooling rates of laser powder bed fusion, and targeting invariant reaction compositions to minimise the propensity for solidification cracking. We perform laser line scans and surface remelts of arc-melted Ti–0.38C, Ti–1.67B, Ti–8.5Si and Ti–32.5Fe wt-% eutectic compositions to assess potential material amenability to the laser powder bed fusion (LPBF) process at low cost as well as determining the nanostructure and hardness properties. The results indicate that MMCs are amenable to LPBF and may outperform conventional alloys.

“…In the context of dispersing secondary particles, intensive analysis has been carried out to find how reinforcement goodness lied in adequate bonding to the matrix and its uniform distribution inside the matrix (Wang et al, 2019;Fang et al, 2021;Mohanavel and Vijayakumar, 2021). In this regard, with the use of ceramic particles, which could react with titanium, the optimal properties of TMCs can reasonably be expected to be achieved.…”

Regarding titanium matrix composites (TMCs), their properties strongly depend on the reinforcement material employed for their manufacturing; this may lead to a multitude of investigations on TMCs. Considering the diverse typology of the reinforcement, six types of ceramic particles were tested in this investigation: B4C, SiB6, TiB2, TiC, TiN, and BN. In order to compare their behaviour and their own influence on the properties of the TMCs, the same ratio was employed in the starting materials, 30% volume. Among the techniques for developing TMCs, a significant number of authors propose Powder Metallurgy as a favourable route. In this framework, the novel Rapid Sinter Pressing technique was employed to perform the present study, due to its flexibility, repeatability, and reproducibility, as well as short-run cycle times. The processing temperature (930 °C) was set with the intention of evaluating how the reinforcements behave differently depending on their reactivity with the Ti matrix. In this regard, the main objective of the research was to carry out a comparison on the behaviour of seven TMCs fabricated with similar operational parameters via RSP.

“…However, most previous studies used pre-alloyed powders, which require long processing cycles, including preparing homogeneous ingots and atomisation processes, which is expensive due to the low powder yield in the optimum size range (approximately 15-60 μm) for LPBF [7]. In situ alloying of the blended powders is, therefore, attractive for the AM fabrication of β-Ti alloys, which has been demonstrated in Ti alloys [12][13][14], steels [15], Ni-based superalloys [16],NiTi alloys [17], and Zn alloys [18]. Using in situ alloying methods, instead of pre-alloyed powders, to process Ti alloys, is cost-effective and offers great opportunities to produce non-conventional alloys [19][20][21][22].…”
