Abstract:	摘要： Rod samples of Mg60Zn35Ca5 bulk metallic glass composites (BMGCs) dispersed with Ti particles have been successfully fabricated via injection casting. The glass forming ability (GFA) and the mechanical properties of these Mg-based BMGCs have been systematically investigated as a function of the volume fraction (Vf) of Ti particles. The results showed that the compressive ductility increased with Vf. The mechanical performance of these BMGCs, with up to 5.4% compressive failure strain and 1187 MPa fracture strength at room temperature, can be obtained for the Mg-based BMGCs with 50 vol % Ti particles, suggesting that these dispersed Ti particles can absorb the energy of the crack propagations and can induce branches of the primary shear band into multiple secondary shear bands. It follows that further propagation of the shear band is blocked, enhancing the overall plasticity. 出版者： MDPI AG 出版日期： 2016-05-01 出處： Metals (Basel ), 2016-05, Vol.6 (5), p.116 資源來源： Publicly Available Content Database 識別號： ISSN: 2075-4701 識別號： EISSN: 2075-4701 識別號： DOI: 10.3390/met6050116
