摘要：

The influence of the initial phase composition on the microhardness of 304 stainless steel before and after boron ion implantation has been studied. The initial phase composition is influenced by the specimen preparation methods used and has been determined using Glancing Angle X-ray Diffraction (GAXD). Electropolishing resulted in purely austenitic (feel specimens. Electropolishing followed by mechanical polishing resulted in the introduction of a martensitic (bcc) phase. Elastic Recoil Detection Analyses (ERDA) was used for boron depth profiling in the steel. The peak concentration of implanted boron was found to be higher in martensitic specimens. These specimens exhibit higher microhardness.
