Elaboration and characterization of yttrium implanted low manganese steel.

Low manganese steel samples were yttrium implanted using ion implantation t echnique. Sample compositions and structures were investigated before and a fter yttrium implantations to determine the yttrium distribution in low man ganese steel. Yttrium implantation depth profiles were characterized using conventional techniques such as X-ray photoelectron spectroscopy (XPS), ref lection high energy electron diffraction (RHEED)I X-ray diffraction (XRD), glancing angle X-ray diffraction (GAXRD) and a nuclear analytical method: R utherford backscattering spectroscopy (RBS). The aim of this study is to sh ow that correlation between composition and structural analyses allows to u nderstand the effect of implanting yttrium in low manganese steel.
