| Abstract: | The law of intermetallics formation of Ti implanted H13 steel is studied.The strengthening mechanism of intermetallics in steel is discussed. The differential equation of ion implantation for vacancies and interstitials and its solution are given.According to this analysis,the Ti implanted samples are obtained using different energy,dose and target temperature. The alloys of Fe_2Ti and FeTi are observed by X-ray diffraction and TEM. The hardness and wear-resistance of the samples are observed.The hardness increases by 40 to 60 per cent.The influence of annealing on intermetallics is given by TEM.The influence of the intermetallics on the strengthening of the samples is discussed. |
