Abstract The method for the determination of alloyed amounts of rare earth metals in steels developed previously by the authors was verified to be appropr ate Using this method, the alloyed amount of Ce in steels 16Mn, 25MnTiB, Cr24Ni7Si2N and Fe-Cr-A1 alloy has been analysed The microautoradiographs show that the alloyed Ce distributed among the pearlite is more than that among the ferrite in 16Mn or 25MnTiB steel. An enrichment of Ce was obviously observed by autoradiography to be segregated along the grain and dendrite boundaries in Fe-Cr-Al alloy or Cr24Ni7Si2N when the Ce content is notl ow The microscopic inhomogeneity of Ce distribution is presented among different grains of the Fe-Cr-Al alloy.
