Abstract MC_sf/Fe and C_fp/Fe powder metallurgy materials were prepared by pressing-vacuum sintering using reduced Fe powder as the matrix, micron short carbon fibers (MC_sf) with a length of about 20 μm and carbon fiber particles (C_fp) with a particle size of 1-4 μm as the dispersoid, respectively. Natural graphite (NG) with an average particle size of 10 μm as the raw material was used to prepare NG/Fe powder materials for comparison. The effects of micronshort carbon fibers and carbon fiber particles on the microstructure, physical properties, mechanical properties and dimensional changes were investigated. The results show that the activity of carbon fiber particles is much higher than that of graphite and degummed short carbon fibers (DC_sf), and the maximum mass loss rate at 800 ℃ in air atmosphere is 3.75 times that of graphite and 16.6 times that of degummed short carbon fibers. Compare with NG/Fe and MC_sf/Fe powder metallurgy materials, the dimensional stability of C_fp/Fe powder metallurgy materials during sintering is greatly improved, with the maximum radial expansion and shrinkage rates of 0.39% and 0.14%, respectively; the strength and toughness are the highest, with the density, flexural strength, shear strength and tensile strength of 6.91 g/cm³, 736.9 MPa, 205.7 MPa and 334.8 MPa, respectively. The elongation reach 10.5%, and the fracture mode of the materials change from a brittle along-crystal fracture to a completely severe nest fracture.

Key words： Fe short carbon fiber sintering shrinkage rate activity mechanical property dimensional change
