A Novel Cemented Hard Alloy Prepared by Mechanical Alloying and Hot‐Pressing Sintering

Owing to its exceptional hardness and superior wear resistance, tungsten carbide (WC) has a wide range of industrial applications. In recent years, many studies have been focused on how to improve the physical and chemical properties of WC, as well as to reduce its high operating cost. One aim of this work was to fabricate the (W0.5Al0.5)C0.5-Co alloy bulk bodies. Hot-pressing (HP) as a common technique is a suitable and economical method to facilitate the sintering of (W0.5Al0.5)C0.5-Co hard alloy. Additionally, the mechanical properties and the microstructures of (W0.5Al0.5)C0.5-Co bulk bodies were tested.
