(Ti,V)Cx材料的制备与表征分析
Preparation and characterization of(Ti,V)Cx composites
摘要
Abstract
In this study,various non-stoichiometric(Ti,V)Cx polycrystalline diamond tool binders were synthesized using titanium carbide(TiC)powder and vanadium(V)powder as raw materials,and employing mechanical alloying technology.The phase composition of the resulting composite powders and their sintered bodies were thoroughly analyzed using X-ray diffraction(XRD)techniques,with further in-depth analysis of the XRD patterns being performed using Jade software.Additionally,scanning electron microscopy was utilized to observe the microstructural morphology of the composite materials,and Vickers hardness tests were carried out to assess their mechanical properties,including hardness and fracture toughness.Experimental results indicated that within the sintering temperature range of 1 300 to 1 600℃,the solid solubility between TiC and V was significantly increased with rising sintering temperature.When the sintering temperature remains constant,an increase in the V content leads to a stable increase in the hardness of the sintered body.Furthermore,under the same sintering temperature conditions,sintered bodies with a higher TiC to V molar ratio exhibited superior fracture toughness compared to those with a lower molar ratio.关键词
