Direct Recycling of Cold Work Tool Steel Swarf into New Cutting Disks via Field‐Assisted Sintering
Advanced Engineering Materials, EarlyView.Through a sintering method known as field‐assisted sintering technology/spark plasma sintering, cold work tool steel swarf can be directly recycled into new cutting disks. This method is capable of densifying the unconventional powder morphology of swarf, and it can also seal grinding contaminants, such as Al2O3, into the steel matrix.
