Appl. Phys. Lett.90,081919(2007) Abstract: The authors report on the dramatic effect of sample size on the plastic deformation capability of a Ti-based bulk metallic glass. Compared with the larger one, the smaller size glassy alloy with the same chemical composition exhibits significantly enhanced plasticity, suggesting a "smaller is softer" trend of metallic glasses. The phenomenon is attributed to the fact that the smaller size alloy, which experienced a faster cooling rate during solidification, contains a larger amount of heats of relaxation and crystallization, favoring the preferential nucleation of shear bands and thus allowing enhanced plasticity upon compressive loading. |

Applied Physics Letters -- 14 May 2007 Appl. Phys. Lett. 90, 201909 (2007) (3 pages) Study on the structural relationship between the liquid and amorphous Fe78Si9B13 alloys by ab initio molecular dynamics simulation Jingyu Qin, Tingkun Gu, Lei Yang, and Xiufang Bian Abstract The structure of the liquid and amorphous Fe78Si9B13 alloys is investigated by ab initio molecular dynamics simulation. The amorphous structure bears a strong resemblance to the liquid structure on both the atomic and electronic levels. Chemical short-range order is evidenced by higher Fe coordinating proportion than the nominal one around both Si and B atoms in both the liquid and amorphous states. The atomic distances and the local densities of states show that Fe–Si bonding is stronger than Fe–B bonding and Si and B tend to repulse each other. |
