Microstructure, mechanical properties and anysotropy of pure ti processed by twist extrusion and cold rolling
(2004) Ultrafine Grained Materials III, 2004 p.457-462- Abstract
It is investigated UFG structure formation in CP Ti bulks processed by SPD (cold Twist Extrusion (TE), true strain e∼5.1, with the following Cold Rolling (CR), true strain e∼0.7). Evolution of microstructure and tensile mechanical properties in the CP Ti were investigated under room temperature. After the TE, in transversal section it is formed structure fragments with size less 1 μm. Strength increased on 80 %; elongation was 3.4 %. Following low-temperature annealing (300°C, 1 hour) leaded to increasing in both strength and ductility properties. In longitudinal section, specimens' strength properties increased slightly. Elongation was about 6 %. The following low-temperature annealing practically did not influence on the strength but... (More)

Following low-temperature annealing (300°C, 1 hour) leaded to increasing in both strength and ductility properties. In longitudinal section, specimens' strength properties increased slightly. Elongation was about 6 %. The following low-temperature annealing practically did not influence on the strength but improved elongation to 7.2 %. The additional CR leaded to forming severe deformed structure. Average size of fragments was 50-500 nm. It was observed elimination of anisotropy and equalization of strength. In both directions ultimate tensile strength became about 780-800 MPa and ductility properties remained the same as in the original.
