摘要：Wide use of titanium (Ti) materials in medicine gives impetus to a search for development newtechniques with elevated properties such as strength, corrosion resistance and Young's modulus close to that of bonetissue. This article presents most recent state of the art on the use of equal channel angular pressing (ECAP) techniquein evolving mechanical characteristics of the ultrafine-grained bio-grade Ti materials. Over past few decades, researchactivities in this area have grown enormously and have produced interesting results, including achieving combinationof conflicting properties that are desirable for biomedical applications by severe plastic deformation (SPD) processing.A review of the most recent work in this area is systematically presented. The challenges in processing ultrafinegrainedTi materials are identified and discussed. An overview of the biomedical Ti alloys processed with ECAPtechnique is given in this review, along with a summary of their effect on the important mechanical properties that canbe achieved by SPD processing. The paper also offers insights in the mechanisms underlying SPD.
