This paper deals with the characterization of three different commercial, WC-Co cemented-carbide tools in form saw blades, one group which exhibits more frequent cracking. Since properties these materials largely depend on microstructure, a detailed was carried out using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and diffraction (XRD). The SEM image analysis ...
Nowadays, cemented carbides-steels joints by brazing method are taken into consideration. One of the problems of these joints is the creation residual stresses that can reduce it with choose correct parameters of brazing. In this study, Silver base alloy filler containing copper, zinc and cadmium have been used in temperature 780°C and the effect of time parameter 5, 10 and 15 minutes on micros...

Cemented carbides, including coated cemented carbides, account for 75% of the cutting tools market because of their features such as high hardness, toughness, and the responsiveness to iron, through the use of tungsten carbide for their main hard phases and cobalt for their bonding metals. The consumption of tungsten continues to increase as the amount of carbide tool production increases with ...

This research work presents the results of an experimental investigation of cryogenically treated, coated and uncoated tungsten carbide cutting tool inserts in turning of AISI 1040 steel. Three different tungsten carbide inserts coated with aluminum chromium nitride (AlCrN), titanium nitride (TiN) and uncoated WC were taken and treated cryogenically. Experiments were performed to evaluate the c...
