Its principle is: in the process of mechanical grinding or ball milling, metal powder, alloy powder, or the mixture of metal powder and alloy powder collides with the grinding ball at high frequency, resulting in repeated deformation, seaming, and fracture to form composite powder. As mechanical grinding or ball milling continues, mechanical ...

Abstract. High-entropy alloys (HEAs) are highly anticipated because of their superb properties in strength, hardness, wear resistance, etc. However, compared with numerous studies on the design and properties of HEAs, the machinability research of HEAs is extremely rare, which limits the application of HEAs. In this work, grinding experiments of (FeCoNi)86Al7Ti7 …
