The matrix composites for diamond tools were tested with such modern testing instruments and equipments as DTA-7 differential thermal analyzer, JCXA-733 electronic probe and scanning electron microscope, JEM 2000 FX Ⅱ transmission electron microscope, eXL energy spectrometer, and humidity test instrument. The analysis, comparison, and induction of the testing results prove the enhancing effects of the rare earth on the matrix composites: degeneration, micro-alloying, purification, and catalytic activation. The comprehensive function of these effects leads to the decrease in the porosity of the matrix composites and to the increase in such actual indexes as the flexural strength, hardness, and impact ductility of the whole rare earth Fe-based diamond tool materials.

The results showed that the second phase was refined and distributed dispersedly in the matrix of the alloy after ECAE. The refined particles could cut the soft matrix, which was useful to grain refinement during ECAE. The dispersoid distribution of the second phase could strengthen the matrix and improve mechanical properties of the alloy.
