ResumoConsolidation and CharaCterisation of hard Metal Powders Milled under diChloroMethanethis work presents the development of a safer processing route for hard metals.traditional processing of fine particles under organic solvents presents significant explosion risks.the milling under dichloromethane (DcM) reduces the risks associated with fire hazards.after milling and drying, the samples have been sintered in an industrial sintering furnace under a vacuum at 1380°c. the materials' characterisation has been done by X-ray diffraction, scanning electron microscopy, particle size analysis, optical microscopy, and by magnetic measurements.the present work results reveal the powders' appropriate properties after milling and drying and the desired biphasic (co-Wc) phases obtained after sintering, thus proving the feasibility of such a route, therefore the diminishing of specific fire hazards.
