“…Ginden et al studied recrystallization in 99.98 pct purity, polycrystalline copper cold-rolled at temperatures of -269°C, -253°C, -196°C, and 23°C. [18][19][20][21] Their results showed that both the primary recrystallization temperatures and the activation energy of recrystallization decreased as the deformation temperatures were decreased.…”

The effects of both deformation temperature and degree of deformation on the deformation texture, recrystallization behavior, and recrystallization texture were studied for cold-rolled, high-purity, polycrystalline nickel. Differential scanning calorimetry was used to determine both the stored energy of deformation and the recrystallization temperature, and electron backscatter patterns were employed to reveal both the deformation and recrystallization textures of nickel rolled to either 90 pct thickness reduction at -196°C, 25°C, and 200°C or rolled to 90, 95, and 98 pct thickness reductions at 25°C. The results show that decreasing the rolling temperature below room temperature increased the stored energy considerably and decreased the recrystallization temperature, whereas increasing the rolling temperature had no effect on either the stored energy or the recrystallization temperature. These different rolling temperatures had little effect on the cube texture produced by primary recrystallization. In contrast, increasing the rolling reduction increased the stored energy (at least from 90 to 95 pct), decreased the primary recrystallization temperature, and also sharpened the primary-recrystallized cube texture.

“…It is well known that the use of plastic deformation at cryogenic temperatures also contributes to structure refinement and thus can improve the mechanical characteristics of metallic materials subjected to SPD [5]. In this connection, the purpose of this work has been to study the impact of drawing at cryogenic temperatures on the structure and mechanical properties of pure titanium.…”

The purpose of this study was to obtain pure nanostructured titanium by drawing at cryogenic temperatures and to investigate its structural and mechanical properties. Titanium rods were obtained by severe plastic deformation under the scheme of upsetting-extrusion-drawing. Upsetting and extrusion were performed at 800 K, obtained rod was initially drawn at 300 K to diameter of 3.7 mm (degree of true strain e = 3.2). Further deformation of the finish drawing was performed at 77 K (liquid nitrogen) and at 300 K.Keywords: titanium / medical implants / plastic deformation / nanostructure / mechanical properties / Das Ziel dieser Arbeit war die Herstellung von reinem nanostrukturiertem Titan durch die Tiefzieh-Verformung bei kryogenen Temperaturen und die Untersuchung seiner strukturellen und mechanischen Eigenschaften. Titanproben (Stäbe) wurden durch die starke plastische Verformung beim Pressen-Extrusions-Tiefziehen hergestellt. Das Pressen und die Extrusion wurden bei 800 K durchgeführt, der erhaltene Stab wurde zuerst bei 300 K zu einem Durchmesser von 3,7 mm gezogen (wahre Dehnung e = 3,2%). Eine weitere endgültige Verformung wurde durch Tiefziehen bei 77 K (flüssiger Stickstoff) und bei 300 K durchgeführt.
