摘要

Powderous crystalline materials of the composition Fe~3- ~xMn~xC have been prepared by first synthesizing Fe ~3C via mechanical alloying in a planetary mill followed by the addition of elemental manganese and arc-plasma melting or via the classic ceramic route in an electric furnace. The milling time for the synthesis of Fe3C was significantly reduced through adjusting the parameters of the planetary ball mill. When the ball-to-powder ratio was lowered, significantly larger batches were possible. Sintering in a fired tubular furnace was found to be the method of choice for the aftertreatment of the nanocrystalline Fe ~3-~xMn~xC powders as exemplified by X-ray Rietveld refinements.
