| Abstract: | The sound velocity of ternary amorphous alloys( Fe_(100-x)M_x)_(83)B_(17) and binary amorphous alloys Zr_(100-x)M_x is determined by means of ultrasonic impulse transmission teehnique(USIPT) and the Young's modulus of these ribbonlike metallic glasses are then given. Alloying element M for the former represents Cr, Mo, W, Zr and Co; for the later represents Fe, Co and Ni. A discussion is made on the composition dependence of sound velocity, on short range order effect and influence of density as well as densification resulted from random packing of atoms with different atomic radius on these parameters. |
