Cemented carbides are composite materials traditionally made of tungsten carbide (WC) and cobalt (Co). The former, referred to as the hard phase, provides hardness, while the latter is the binder and provides toughness. This combination of properties makes cemented carbide suitable for applications such as rock drilling or metal cutting. Since Co is classified as a critical raw material by European Union, and recent studies find out that is dangerous for human health, this research investigates an alternative binder system for WC cemented carbides as a potential substitute for Co. The focus is put on a system based on Iron, Nickel and Co, with a ratio of 50-25-25 wt%.
