“…Apparently, repeated processes of destruction and cold welding [27] during HEBM led to the accumulation of defects as well as to a decrease in the diffusion distance between Hf, Zr, and C in Hf/Zr/C composite particles and, consequently, to a decrease in the activation energy and increase in the reactivity of the mixture. Intense local heating due to friction forces, accumulated defects, and high exothermicity of the powder mixture [28,29] contributed to the initiation of a self-propagating reaction inside the jars, as a result of which the (Hf,Zr)(C,N) product was formed instantly. However, it should be noted that after 10 min, the reaction was incomplete.…”

Nanostructured single-phase hafnium-zirconium carbonitride powders were synthesized using a simple and fast mechanochemical synthesis approach. The critical milling duration, after which a (Hf,Zr)(C,N) solid solution formation inside a jar occurred via mechanically induced self-sustained reaction (MSR), was 10 min. After 30 min of treatment, a solid-gas reaction was completed, and as a result, a homogeneous (Hf,Zr)(C,N) powder consisting of 10–500 nm submicron particles was obtained. The phase and structure evolution of the powders after different treatment durations allowed for the establishment of possible reaction mechanisms, which included the formation of Hf/Zr/C-layered composite particles, their interaction via MSR, and further grinding and nitridization. Spark plasma sintering (SPS) was used to produce bulk hafnium-zirconium carbonitride ceramics from nanostructured powder. The sample had higher values of relative density, hardness, and fracture toughness than those for binary compounds of a similar composition.

“…Chicardi et al 25 used Ti, graphite, and boron powders as raw materials to prepare Ti(BCN) ceramic powder by high-energy ball-milling technology in nitrogen atmosphere. Ti(BCN) is composed of nano-ceramic particles, and the distribution of boron, carbon, and nitrogen in Ti(BCN) phase is highly uniform.…”

In order to study the solid‐solution process between amorphous BCN and metal Ta, Ta(B, C, N), (Ta, Nb)(B, C, N), and (Ta, W)(B, C, N) ceramics were prepared by high‐energy ball milling, and their phase composition, microstructures, and binding bonds have been analyzed. The results show that all the three ceramics are hard agglomeration state, formed by stacking of nanoparticles. The mechanical alloying process is accompanied by the formation of chemical bonds, such as B–Ta, N–Ta, C–Ta, and O–Ta for Ta(B, C, N) ceramic, and the order of solid solution is C > N > B. When heated at 1500°C, a second diboride phase precipitates from (Ta, Nb)(B, C, N) ceramic, whereas the second phase of WC gradually dissolved from (Ta, W)(B, C, N) ceramic. This work provides theoretical and data supporting to analyze the solid‐solution process of Ta(B, C, N) ceramic.
