The work is devoted to the study of the influence of high cooling rates on the structure formation and mechanical properties of the biosoluble Mg-Zr-Nd alloy used for the manufacture of biosoluble implants. It was determined that the ultrahigh cooling rate (about
55 oC/sec), leads to the formation of superfine structure and even distribution of strengthening phases significantly improving the mechanical properties of the alloy. Based on the data of microstructure simulation, a regression equation was constructed, which allows to predict the average grain size of the alloy. The obtained empirical dependences allow to predict and obtain the final alloy with a wide range of possible mechanical properties, favorable for performing various tasks facing biosoluble implants and using the most available casting methods. Industrial-grade biosoluble implants have been preclinically tested and recommended for further use.
