MICROSTRUCTURE EVOLUTION OF PURE TITANIUM DURING ECAP
Journal Title: Materials Engineering - Materialove inzinierstvo (MEMI) - Year 2011, Vol 18, Issue 3
Abstract
The main goal of the presented paper was to describe deformation behaviour of the commercial purity titanium during the ECAP method. Attention was paid particularly on reached mechanical properties of above mentioned material. Design of experiments rested in extrusion at temperature in range from room temperature up to 280°C. The way of approach was planned in investigation of imposed strain accumulation ability. Among used methods for determination of intended aims were tensile tests, TEM, SEM. Mechanical properties were evaluated using standard tensile tests as well as small punch tests. Correlation between mechanical properties from tensile test and punch test was developed. Depending on imposed strain (e = 2 up to 8) was found that mechanical properties (namely tensile strength) have increased up to 960 MPa. Developed ECAP process enables controlling morphology of microstructural constituents and workability of titanium Grade 1.
