У статті описана мікроструктура, фазовий стан фізико-механічні властивості біомедичної сталі 316L, виготовленої 3D-друком за адитивною технологією Laser based-powder bed fusion у порівнянні із катаним варіантом. Встановлено, що друкована сталь має аустенітну структуру гетерогенної будови, особливості якої залежать від площини аналізу відносно напрямку друку. Завдяки наявності нерівноважної дисп...

In view of the high sensitivity to microstructure evolution higher harmonics generated by nonlinear ultrasonic method, tensile damage in stainless steel AISI 316L was evaluated Lamb wave. The effect different degree deformation on response analyzed considering and test results. First, power-law relation parameter plastic strain is proposed. Meanwhile, martensitic transformation increasing dislo...

In the present study we performed anodization of stainless steel AISI 316L varying voltage, time and H 2 O concentration in electrolyte obtaining self-ordered porous oxides. Open-circuit potential measurements, potentiodynamic polarization electrochemical impedance spectroscopy were 0.1 M SO 4 , NaCl NaOH electrolytes. The metallic substrate underneath grown oxide was also characterized. result...

In this paper, we investigate the possibility of using friction method for modifying microstructure and mechanical properties in near-surface regions AISI 316L austenitic steel specimens purpose its practical application. It is shown that a region severe plastic deformation arises near surface, which transforms initial fine-grained polycrystalline structure into homogenized zone consisting defo...

Rat bone marrow cells were cultured in experimental conditions that favour the proliferation and differentiation of osteoblastic cells (i.e., 2.52 x 10(-4) mol l(-1) ascorbic acid, 10(-2) mol l(-1) beta-glycerophosphate and 10(-8) mol l(-1) dexamethasone) in the absence and in the presence of stainless-steel corrosion products, for a period of 18 days. An AISI 316L stainless-steel slurry (SS) w...

In this study, double loop electrochemical potentiokinetic reactivation (DLEPR) test was applied to determine the degree of sensitization in 316L type stainless steel, where obtained results were correlated with revealed microstructures after oxalic acid test and weight loss measurements of Streicher and Huey acid tests. Best agreement was provided with test parameters which are 1 M H2SO4 and 0...
