What is Ti3AlC2? Ti3AlC2: Commercially available Ti (titanium), Al (aluminum), and C (graphite) powders were used as raw materials. The technical characteristics of these as-received materials are presented in Table 1. The Ti, Al, and C powders with a stoichiometric ratio of 3:1:2 for Ti:Al: C were mechanically activated by dry ball-milling (Retsch PM100) for one h. The SEM images of morphology and XRD patterns of as-purchased titanium, aluminum, and graphite powders are shown in Fig. 1. According to Fig. 1a, the size of titanium particles is < 40 µm, as declared by the supplier, and the morphology of particles are irregular and angular. XRD analysis identified Ti as the unique crystalline phase in this powder material.
The synthesis of pure Ti3AlC2 The synthesis of pure Ti3AlC2 products still needs to be solved. The self-propagating high-temperature synthesis (SHS) possesses several benefits, including short reaction time, favorable exothermic reaction, and simple equipment requirements. Zhou et al. synthesized the Ti3AlC2 compound by the SHS method for the first time using the elemental Ti, Al, and C (carbon black) powder mixture. They claimed that an essential requirement for the synthesis of the MAX phase is a very high heating rate to avoid the formation of TiC and Al as final products. Although using the basic materials, achieving the pure outcomes by the SHS technique is also tricky; employing titanium carbide and intermetallic compounds as the raw materials were reported to assist in approaching the pure Ti3AlC2. The addition of Al4C3 to the elemental powder mixture was found to decrease the reaction temperature and enhance the degree of Ti3AlC2 formation. The synthesis mechanism of Ti3AlC2 prepared by the SHS method was investigated by Sun et al. They found that TiC and TiAl have an essential effect on the synthesis of Ti3AlC2. The Ti3AlC2 content rises with higher amounts of TiC or TiAl in the starting mixture. Ge et al. also described the formation mechanism of combustion-synthesized Ti3AlC2 from the elemental powders. The preformed TiC crystallites dissolve in the molten Ti–Al, and afterward, Ti3AlC2 precipitates from the melt and grows to a layered-structure state.
The preparation of Ti3AlC2 MAX phase Mechanically-activated self-propagating high-temperature synthesis (MASHS) method consists of a short time high energy ball milling stage before the SHS process. This step increases the reactivity of the as-milled powders and raises the purity of products. This method is used successfully to prepare intermetallic parts and MAX phases. The work focuses on preparing the Ti3AlC2 MAX phase, employing the MASHS process on the elemental aluminum, titanium, and carbon (graphite) powders. In this way, two MASHS processes (wave propagation mode using a reaction chamber and thermal explosion mode using a tubular furnace) are compared to determine the optimized synthesis procedure.
