Abstract: The specimen preparations of mechanical alloyed Fe-C-Ti powders have been discussed,thier morphologies and microstructures have been studied.The results shows that the powder particle size increased at the beginning of mechanical alloying and then decreased,the powder morphology also underwent a sphere spindle sphere change.After vacuum heat treatment of the composite particles,it was clarified that TiC particles were precipitated in matrices and the size of TiC particles at interfaces was bigger than that in crystals.
