“…A) As the most simple structure, a various kind of pure metals of high and commercial purity such as aluminum, [87][88][89][90][91][92][93][94] copper, 6,37,[95][96][97][98][99][100][101][102][103][104][105][106] iron, 76,107) titanium, [108][109][110][111][112][113][114] magnesium, 34,72,[115][116][117] have been processed by SPD for corrosion studies. In this simple system, grain size or grain boundary density impacts the corrosion resistance as a primary metallurgical variable with very few other metallurgical changes involved.…”

“…[108][109][110]112,127,155,[184][185][186] Recently, other SPD processing emerged such as hydraulic extrusion (HE), 111) severe-or cryo-cold rolling. 45,75,76) These SPD processing generates UFG metals in bulk form, but in other processing, UFG or nanocrytallization can be achieved in the surface layer using high power shot blast, 78) ultrasonic peening, 77,79,80) surface mechanical attrition treatment (SMAT), [72][73][74] burnishing/brushing, [82][83][84] and friction stir processing (FSP).…”

“…For instance, the following authors reported on percentage increase of tensile strength of biomedical titanium alloys processed by HPT; Ashida et al [32] on Ti-6Al-7Nb (19%) , Jiang et al [33] on Ti-5Al-5Mo-5V-3C(14.6%) and Sharman et al [34] on Ti-24Nb-4Zr-8Sn (50%). Nie et al [35] worked on corrosion behavior of CP-Ti processed by HPT at 6GPa, 10 passes. Results showed that, there was a decrease of grain size from 10µm-110nm with increased dislocation density.…”

“…Отметим, что зависимость ско-рости коррозии от размера зерна в титане и титановых сплавах имеет сложный и неоднозначный характер -для одного и того же материала описано как повышение, так и уменьшение коррозионной стойкости при измельчении зеренной структуры. Например, в работах [5,6] было об-наружено снижение коррозионной стойкости мелкозернистого титана; в [7][8][9][10] было показано, что формирование мелкозернистой структуры позволяет повысить коррозионную стойкость титана; в работах [11][12][13] однозначную связь установить не удалось. Причины этой неоднозначно-сти обусловлены, на наш взгляд, тем, что на развитие МКК в титановых сплавах влияет не только размер зерна, но и локальный химический состав границ зерен.…”
