Consolidation of binderless nanostructured titanium carbide by high-frequency induction heated sintering

Mechanical properties and consolidation of binderless nanostructured (Ti,Cr)C from mechanochemically-synthesized powder by high-frequency induction heating sintering

“…Comparing the above study with the present, the sintering temperature and time of the high-frequency induction heated sintering are lower and shorter, respectively than those of plasma activated sintering. The fracture toughness (7.8 MPa m 1/2 ) of (Ti,Cr)C in this study is higher than that of monoclinic TiC [2]. Fig.…”

“…These properties have led to TiC being used extensively in cutting tools and as a composite abrasive material with a binder metal such as Ni. The low toughness of titanium carbide, however, leads to structural failures during high-speed machining, resulting in a shortened tool life [1,2]. One approach, commonly utilized to improve fracture toughness, has been to form solid solution carbide and make nanostructured materials [3].…”

The effect of graphene reinforcement on the mechanical properties of Al2O3 ceramics rapidly sintered by high-frequency induction heating

“…Powders of three compositions corresponding to alumina, alumina-1 wt.% graphene, and alumina-3 wt.% graphene were prepared by weighting and milled in a high-energy ball mill (Pulverisette-5 planetary mill) at 250 rpm for 10 h. WC balls (9 mm in diameter) were used in a sealed cylindrical stainless steel vial under an argon atmosphere. We previously reported that a significant contamination did not occur from the WC milling media and stainless vessel [24]. Therefore, in this study, we used WC balls to minimize contamination.…”

“…Fig. 4 shows plot of B r (B crystalline + B strain ) cosθ versus sinθ in Suryanarayana and Grant Norton's formula [24] for particle size measurements. The average grain sizes of the alumina in the alumina, alumina-1 wt.% graphene, and alumina-3 wt.% graphene powders were calculated as about 62, 43 and 31 nm, respectively.…”

Thermal Analyses for Induction Sintering of Powder Metal Compacts up to Sintering Temperature

“…Shon et al [8] investigated the sintering of TiC without the use of a binder by the high frequency induction heated sintering (HFIHS) method. The aim of their research is to produce dense fine grained binderless TiC hard material.…”
