Abstract
⺠Grain size of pure Ti was reduced to â¼130 nm from â¼8.6 μm using high pressure torsion (HPT). ⺠Microhardness was improved from 182 HV1 to 305 HV1. ⺠Micro wear behavior of HPT processed Ti was studied for the first time. ⺠Wear of coarse grained Ti was dominated by ploughing and wedge forming, while wear of HPT processed Ti was dominated by abrasion. ⺠HPT processed Ti has more homogeneous wear scar and lower wear rate.
