Objective. To perform comparative study of composition and strength properties osteoplastic biomaterials subjected to technological processing. Material Methods. Specimens native (initial) deproteinized bone tissue were analyzed. Strength specimens studied by single-axis static extension with automatic recording load curves. Load-extension curves used calculate mechanical parameters: proportionality limit, relative deformation before destruction, the Young’s module. Dependence between a...
Introduction. Today, bioresorbable magnesium alloys possessing the required physical, mechanical, corrosion, and biological properties, are promising materials for orthopedic cardiovascular surgery. The addition of rare earth elements such as yttrium, neodymium, cerium to improves its properties. Compared widely used titanium alloys, have a number advantages. Bioresorbable slowly dissolve in body, recurrent operation remove implant is not needed. Biocompatible fairly low elastic modulus (10...
Introduction. The interest of modern medical materials science is focused on the development beta-alloys ternary systems (TNZ) based titanium, niobium and zirconium with low Young’s modulus, which comparable elastic modulus bone. A wide application above alloys in medicine limited by its insufficiently high strength properties, such as yield strength, ultimate fatigue life, etc. formation bulk ultrafine-grained structure via deformation processing, including severe plastic deformation,...
The regularities in accumulation and dissipation of energy plastic deformation the samples titanium Zr–1 wt % Nb alloys coarse-grained ultrafine-grained states were studied using temperature curves obtained by IR thermography. New experimental data have been indicating a significant influence state on development strain fracture processes Ti Zr–1Nb alloys.
Выполнено исследование влияние экструзии на механические свойства биомедицинских сплавов основе систем Mg-Y-Nd и Mg-Ca. Сплавы деформировали методом горячей обратной экструзии, накопленная деформация составила e=1,46. Показано, что в результате сплавах формируются дисперсно-упрочненные частицами Mg24Y5 Mg2Caбимодальные структуры, состоящие из зерен a-фазы магния со средним размером 14 9 мкм соответственно для Mg-Ca с размерами менее 1 обоих сплавов, объемная доля которой 22 50 %,...
