“…The addition of TiAl to TiC significantly improves the fracture toughness of cemented TiC, without greatly decreasing the hardness. Also comparing this investigation of TiC-5 vol%TiAl, and TiC-10 vol%TiAl with a study of WC-10Co and WC-10Ni, 23) there is little difference in fracture toughness, but the hardness in this study is higher, than that in the other study.…”

For the formation of composite structures, Co or Ni is added as a binder, in the case of cemented TiC. However, the high cost of Co or Ni, and the low corrosion resistance of TiCCo or TiCNi cermet have generated interest in recent years to find alternative binder phases. It has been reported that aluminides show higher oxidation resistance and hardness, and cheaper materials, compared to Co or Ni. Using a high-frequency induction heated sintering (HFIHS) method, the densification of TiC and TiCTiAl hard materials was accomplished within 3 min. The advantages of this process are the prohibition of grain growth in nano-structured materials, and the rapid densification to near theoretical density. Highly dense TiCTiAl hard materials with a relative packing density of up to 100% were obtained by HFIHS, under a pressure of 80 MPa. The average grain size of the TiC was lower than 100 nm. The addition of TiAl to TiC significantly improves the fracture toughness of cemented TiC, without greatly decreasing the hardness.

“…However, Ni metal phase also had shortcomings in virtue of its poor wettability with ceramic particles. 13,14 Yang et al 15 studied the influence of Ni and Cr on microstructure evolution and densification behavior of Ti(C, N)-based cermets. 9 The content of Mo cannot exceed 4.0 wt% because it was adverse to mechanical properties of Ti(C, N)-based cermets.…”

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.

“…Recently, a plethora of fast sintering techniques including spark plasma sintering (SPS) [11,12], microwave sintering [13] and high frequency induction-heated sintering (HFIHS) [14][15][16] have been developed or optimized and particle growth can be efficiently suppressed by using these techniques since sintering processes can be achieved in a much shorter time and at a relatively lower temperature than those by using a traditional approach. Bao et al [17] fabricated WC-8Co cemented carbides of nearly full densification by microwave irradiation and suggested that the WC grain size and distribution are determined mainly by the sintering temperature in the microwave sintering.…”

-Sample parts with WC-6Co cemented carbides were manufactured successfully with a novel method called coupled multi-physical-fields (electric field, temperature field and force field) activated sintering technology, using a Gleeble-1500D thermal simulation machine. Effects of sintering temperature on the densification, microstructures and hardness of samples were investigated. It was found that densification of the samples was enhanced with the increase of the sintering temperature and a relative density of as high as 98.76% achieved when a sintering temperature of 1200°C was used. The particle size of the WC in sintered samples increased from 1.837 lm to 2.897 lm when the temperature was increased from 1000°C to 1200°C, resulting in the decrease of the hardness from HRC 63.5 to HRC 61.7. The presented work shows that, potentially, coupled multi-physical-fields activated technology is able to produce hard alloys to meet the engineering applications.
