“…W-TCP bioeutectic can be grown by LFZ melting as ceramic or glass, depending on the growth conditions [4]. They both have shown the capability to generate a hydroxyapatite (Hap) layer in simulated biological conditions (SBFs) and have been applied for bone repair, as reported by De Aza [12][13][14].…”

In this work, we have developed and characterized a ceramic composite based on a core of directionally solidified calcium zirconate-calcium stabilized zirconia (CZO-CSZ) eutectic composite coated with a bioactive glass-ceramic. The aim is to research new orthopedic implants as an alternative to conventional 3Y-TZP bioinert ceramics. The CZO-CSZ eutectic rods were grown from the melt of rods of CaO-ZrO2 in the eutectic composition using the laser floating zone technique (LFZ). The mechanical results indicated that directional eutectics prepared with this technique exhibited good mechanical strength and significant hardness and toughness. The LFZ technique was also used to melt the bioactive coating previously placed by dip coating on the CZO-CSZ rod surface. Depending on the thickness of the coating and the applied laser power, an alloying or coating process was achieved. In the first case, the coating was diluted with the surface of the eutectic cylinder, leading to the segregation of the calcium zirconate and zirconia phases and the formation of a bioactive phase embedding zirconia particles. In the second case, a layer of ceramic glass was formed, well attached to the eutectic cylinder. These layers were both studied from the microstructural and bioactivity points of view.

“…Eutectic points occur at particular compositions in materials where two or more solid phases have a single melting temperature. There has been considerable research on eutectic points in alloys in the past several decades, [1][2][3][4][5][6][7][8][9] including substantial ones on the applications of eutectic systems in various fields. [7,10] These studies have shown that the inclusion of eutectic structures can result in improved alloy properties, including lower corrosion rate, [11] higher strength, [10,[12][13][14] and plasticity.…”

“…[19] Moreover, alloys and metallic glasses have also been studied at a microscopic level to determine the influence of eutectic phases on mechanical behaviors through experiments as well as Scanning Electron Microscopy (SEM) and Energy Dispersive x-Ray Spectroscopy (EDS). [2,4,8,20] Because of the comprehensive properties of eutectic compositions, there have been many attempts to fabricate and manufacture materials with eutectic compositions. [21][22][23] Therefore, the determination of eutectic points becomes crucial for such purposes.…”

Eutectic materials have long been an area of interest, and the identification of eutectic points is crucial in materials design to utilize their unique properties. In multicomponent systems, finding eutectic points can be challenging due to the complexity of the systems, and the traditional CALPHAD method lacks efficiency in such tasks. Therefore, a high-throughput CALPHAD method utilizing TC-Python was applied to identify eutectic points in the present work using the Al-Mg-Zn-Cu system as a case study. The proposed method was tested in binary, ternary, and quaternary systems for its reliability and accuracy in predicting eutectic points. In addition, two screening approaches were developed to examine the results and determine the eutectic points. Results showed that the high-throughput method was able to identify a eutectic point in the Al-Mg-Zn-Cu quaternary system with the composition 50Al-14Mg-23Zn-13Cu. Binary and ternary results matched well with existing data, and the quaternary result showed the high-throughput method's capability in other quaternary or even higher-order systems.
