摘要：

The purpose of this study is to investigate the elastic -plastic behavior of inclusions, i.e. SiO3 particles, in cold drawn wire using reverse analysis and nanoindentation test. First, the nanoindentation tests were performed to obtain indentation load P penetration depth Fr curves. Second, the reverse analysis which is consisted of various dimensionless functions including change in E*/sigma(r), W-p/W-t, and a was used to extract the elastic -plastic properties of the indented inclusions and metals from indentation responses. To verify the accuracy of calculated properties, uniaxial tensile tests were performed for different materials which are AISI 1045 and AISI 1080. Results (E, cr n) of tensile tests for each material were also compared with those of nanoindentation tests.
