In the search of nanocrystallinity in tool-steel chips
Abstract
Proper waste handling and sustainable recycling approaches are emerging topics for environmental safety and ecomanufacturing technologies. Steel chips resulting from new machining procedures are good candidates as new raw material for innovative recycling approaches due to their unique characteristics. The objective of this study was to characterize as-quenched H13 (AISI- SAE) tool steel chips produced by a machining procedure. Microhardness tests, SEM/EBSD and TEM techniques were used for hardness evaluation and microstructural characterization. Chips display a highly strained submicron-nanocrystalline grain structure with hardness up to 6.2 GPa. Such characteristics suggest the chips are suitable for powder manufacturing processes such as ball milling instead of atomization process. © 2017 Portuguese Society of Materials (SPM)
