摘要：

High speed steel AISI M2 was obtained by high energy milling from the elemental powders. The kinetics of synthesis were followed by Mossbauer spectroscopy and X-ray diffraction. About 14 h are required to complete alloying (12 at.% solute content) of the matrix and formation of carbides (M6C and Fe3C) all having grain sizes below 20 nm. The mean particle size was 50 mu m and the individual particles were almost fully dense. Limited grain growth to < 100 nm at temperatures up to 1300 degrees C was observed. This new concept for the fabrication of alloys and materials is suggested to be termed mechanomaking. (C) 1998 Elsevier Science S.A. All rights reserved.
