“…Gray phase presented a continuous distribution in the microstructure, while black phase and white phase of different particle sizes were distributed in the gray phase. 46 Therefore, the volume fraction of the solid solution in Figure 8B was more than that in Figure 8A. It should be noted that the gray phase was mainly composed of solid solution as mentioned above.…”

A kind of Ti(C, N)‐based cermet tool material was prepared by microwave sintering. The influence of metal phases (Ni, Co, and Mo) on densification and mechanical properties was studied by orthogonal test. The results indicated that Co was more significant in improving relative density and fracture toughness than Ni, while Ni and Co had the similar effects on increasing the hardness of Ti(C, N)‐based cermet. Mo can improve fracture toughness but decrease hardness. Ti(C, N)‐based cermet with 6 wt% Ni, 6 wt% Co and 6 wt% Mo (TN6C6M6) had the optimal comprehensive mechanical performances, and its fracture toughness and hardness were better than that of Ti(C, N)‐based cermet prepared by conventional sintering. The increasing of sintering temperature promoted the uniformity of microstructure and significantly improved densification and hardness of the Ti(C, N)‐based cermet. The highest fracture toughness of TN6C6M6 (12.41 ± 0.33 MPa·m1/2) was achieved when sintered at 1600°C. For the microwave‐sintered Ti(C, N)‐based cermet, heat preservation period had little effect on densification. The relative density can reach up to 98.6% even though the heat preservation period was 0 minute.

“…Meanwhile, the content of solid solution increased with the extension of heat preservation period. 46 Therefore, the volume fraction of the solid solution in Figure 8B was more than that in Figure 8A. The increased content of solid solution reduced the adjacency of the hard phase, so the plasticity of cermet was improved.…”

“…Composition of (Ti,W)(C,N) in the grayish rim was caused by the dissolution and precipitation process, namely compounding of the cermet. During liquid sintering, the grayish rims took shape [ 29 ]. As shown in Table 2 , the bright cores were embraced by grayish rim structures.…”

In this study, a Ti(C,N)-based cermet material was prepared through vacuum sintering. The research also investigates how holding time and maximum sintering temperature influence the material microstructure and mechanical properties. X-ray diffraction (XRD), energy dispersive spectroscopy (EDS) were used to analyze the composition of the cermet. The microstructure of the cermet was analyzed and examined using a scanning electron microscope (SEM). A Vickers hardness tester was used to test the mechanical properties of the materials. As indicated by testing results, the hardness of the material decreases as the temperature of sintering increases, and its fracture toughness increases gradually as holding time increases. Ti(C,N)-based cermet manifested the optimal mechanical properties when sintering was conducted under 1400 °C with 80 min of holding time. Moreover, the material microstructure is significantly affected by the sintering process. The grain size of Ti(C,N) cermets increases as the sintering temperature increases. The microstructure tends to be uniform and the complete core-rim structures are established as the holding time increases.

“…In order to increase the hardness and the mechanical properties at high temperature of such cutting tools, addition of Mo, Ni-Co, WC, TaC, HfC has been proposed in [66] and their effect has been evaluated through microstructural characterization, which is directly connected to the mechanical behavior of the system. As Ni-Co content increases the microstructure of the material become finer; more than 4% of Mo addition has a negative effect on the mechanical properties.…”

Among other materials, hard metals represent an important family of functional materials. They show properties that are combinations of those of their constituents. The general idea while using hard metals is to exploit their excellent properties in terms of hardness, toughness, wear resistance, and chemical stability. These characteristics made hard metals as promising candidate for use as a cutting tool, which constitutes their main area of application. Depending on the particular use, the most important properties can be achieved: (i) by properly selecting the constituents made up the whole composition, (ii) by varying the relative composition of the phases, or (iii) by applying a suitable hard metal coating layer on the top of the cutting tool. This chapter presents a general overview of the actual scenario concerning different tool materials, including a short history and description of state-of-the-art techniques as regards their composition, their manufacturing routes and their most important properties. Some results of the own research in this field are carried out during the years will integrate this part.
