摘要：
Effect of HPT and accumulative HPT on the Ti18Zr15Nb biomedical alloy has been studied. According to the XRD and TEM data, the beta-phase is a main phase in the alloy both in the initial state and after processing by HPT and accumulative HPT. The beta-phase X-ray line width after HPT processing, and especially after ACC HPT processing has drastically increased as a result of an increase in defect concentration and grain refinement. According to TEM, the grains after HPT processing for n = 10 revolutions are refined in some regions down to 10-30 nm. As a result of HPT processing, the alloy's microhardness has noticeably increased, which indicates an increase in strength and yield stress together with the preservation of the fl-state.
