Mechanical Properties And Corrosion

Due to high strength, perfect plasticity and higher hardness, bulk metallic glass (BMG) has been widely concerned. The work used the vaccum casting of copper-formed mold to establish (Ti36.1Zr33.2Ni5.8Be24.9)100-xCux, where x = 3, 5, 7, 9 and 11. Thermal properties, mechanical behaviors of compression, and corrosion resistance in the proposed compounds were investigated. The results show that the increase in Cu content enhances the heat resistance and the forming of glass of BMGs, small amount of fine dendritic crystals presents in BMG when x = 3, and the best corrosion resistance and mechanical properties can be obtained when x = 7, the yield strength, fracture strength and plastic strain can reach 1496.15 MPa, 2003.44 MPa and 19.19%, respectively.

Mechanical Parameters

Microstructure, mechanical properties, corrosion resistance, and biocompatibility were studied for rapidly cooled 3 mm rods of Zr40Ti15Cu10Ni10Be25, Zr50Ti5Cu10Ni10Be25, and Zr40Ti15Cu10Ni5Si5Be25 (at.%) alloys, as well as for the reference 316L stainless steel and Ti-based Ti6Al4V alloy. Microstructure investigations confirm that Zr-based bulk metallic samples exhibit a glassy structure with minor fractions of crystalline phases. The nanoindentation tests carried out for all investigated composite materials allowed us to determine the mechanical parameters of individual phases observed in the samples. The instrumental hardness and elastic to total deformation energy ratio for every single phase observed in the manufactured Zr-based materials are higher than for the reference materials (316L stainless steel and Ti6Al4V alloy). A scratch tester used to determine the wear behavior of manufactured samples and reference materials revealed the effect of microstructure on mechanical parameters such as residual depth, friction force, and coefficient of friction. Electrochemical investigations in simulated body fluid performed up to 120 h show better or comparable corrosion resistance of Zr-based bulk metallic glasses in comparison with 316L stainless steel and Ti6Al4V alloy. The fibroblasts viability studies confirm the good biocompatibility of the produced materials. All obtained results show that fabricated biocompatible Zr-based materials are promising candidates for biomedical implants that require enhanced mechanical properties.
