Titanium-magnesium based composites: Mechanical properties and in-vitro corrosion response in Ringer's solution

摘要: Abstract Ti–Mg composite rods exhibiting both bioinert and biodegradable characteristics have been manufactured by hot rotary swaging from elemental powders of titanium magnesium. As a result processing, spherical magnesium elongated in the direction deformation dendritic structure starting transformed into highly equiaxed grains. Magnesium particles outer layer composites were decorated thin MgO while interior parts free oxides. expected, Young's moduli, yield peak strengths observed to decrease with an increase content, ductility was enhanced decreasing amount titanium. Composites fractured at angle 45° loading axis along particle boundaries through via transgranular type fracture accumulation twins near surface Mechanical properties be comparable that bone exhibited character upon testing Ringer's solution such selectively corroded pores formed prior powder sites preserved its skeleton structure. In addition, it found volume ratio magnesium, continuous are most important parameters which should considered designing alloys appropriate corrosion rate.
