Degradable Mg-Y-Nd-Mn alloys modified by Sc and Zn

Popis výsledku v původním jazyce

Magnesium alloys have been recently recognized as a biodegradable material for bone substitute application. Degradation rates of Mg alloys in the physiological environment, mechanical properties and cytocompatibility are interesting research topics up tonow as their combination limits most clinical applications. At least the first two properties are in a direct connection with structure and microstructure of proposed materials. Two variants of the commercial WE-type alloy (Mg-Y-Nd-Zr) modified by Mn addition and Zr absence and alloyed with either Sc or Zn were studied in the as cast as well as in the T5 condition in this work. Yield tensile stress and ultimate tensile stress values at room temperature for both alloys studied after the T5 temper are comparable with those in the T6 treated commercial WE43 alloy. Hardening is caused by precipitation of prismatic plates non-uniformly distributed in matrices of both alloys. Ductility of both alloys regardless the treatment increases essent
