This study investigates the influence of milling parameters and sintering cycle on microstructure properties cemented carbides with an overal WC–11.5wt%Fe–4wt%NbH–0.5wt%C starting powder composition. The raw material powders were milled mixed in a ring mill or planetary ball sintered at 1150, 1200 1250 °C using spark plasma (SPS). carbide density, Vickers hardness fracture toughness evaluated. ...

The ultra-short pulse laser has attracted attention as an advanced tool for functionalizing surface topography, since it has high accuracy and results in little damage. In a previous study, some innovative patterns were introduced on cemented carbide surfaces, such as dimples, which are commonly used as oil reservoirs for bearings. The accuracy is not only related to the inherent features of th...

The concrete community in the United States has reached the point where it needs a standard test for measuring the fracture toughness of concrete. A concrete standard might be obtainable by adapting existing standards for cemented carbides and rock. These standards use the short rod specimen geometry and two associated test methods. The combination of specimen geometry and test methods may have...

This paper aims to provide a summary of metal injection moulding technologies utilising cemented WC-Co carbides comprised grain growth inhibitors (GGI). The advanced manufacturing (MIM) has the ability produce cement nanostructured carbides. In addition, nature feedstock plays crucial role when defect-free component at each point MIM phase, thus interactions between powder and binder combining,...

Laser ablation has become an innovative treatment for cemented carbides, regarding edge rounding and surface modification, aiming to improve their tribomechanical performance. Meanwhile, the precision offered this technique also positioned it as effective mean generate micronotches used evaluation of mechanical properties in structural materials. However, similar approach not been attempted har...
