Abstract
AbstractThe compression behavior of Zr15Al5Ni57Y23bulk metallic glass is investigated at room temperature usingin-situhigh pressure energy dispersive X-ray diffraction with a synchrotron radiation source. The structural information of the atomic configuration about Zr15Al5Ni57Y23bulk amorphous alloy such as coordination number (CN), neighbor atomic distance is gained by Fourier transformation under different pressure. The investigation shows that the structure of Zr15Al5Ni57Y23bulk metallic glass is stable under the pressure ranging from zero to 31.7 GPa, but the degree of short-range order changes by the pressure altering the second and the third nearest neighbor local atomic configuration of the amorphous alloy.
