摘要

The effects of FeCr particulates (FeCr_p) on microstructure, and thermal and mechanical properties of powder metallurgy Cu-Sn metal matrix composites were investigated using scanning electron microscopy, energy dispersive spectrometry, X-ray diffraction, differential thermal analysis, low cycle fatigue testing, hardness measurements, and Charpy V notch impact testing. Carbides of type M_(23)C_6 and M_7C_3 were precipitated around the FeCr_p in the matrix of the alpha-Cu-Sn alloy increased and the toughness of the samples decreased The electrical resistivity of sintered specimens was measured in the temperature interval 298-328 K, and in this temperature interval it was seen that the FeCr_p increased electrical and thermal resistance.
