| 中文摘要 | We performed the dynamic mechanical relaxation measurements in typical metallic Zr(46.75)Ti(8.25)CU(7.5)Ni(10)Be(27.5) and Ce(70)Al(10)Cu(20) supercooled liquids close to their glass transition temperature T(g). An obvious excess wing is observed both in temperature- and frequency-dependent loss modulus curves by the calculation of the relaxation time of cc-relaxation in supercooled liquids using the Kohlrausch-Williams-Watts equation in combination with the Vogel-Fulcher-Tamman equation. The results support that the slow beta-relaxation process exists in the metallic liquids and the excess wing is the high-frequency flank of the beta-relaxation. The existence of beta-relaxation in the metallic supercooled liquids affirms that the beta-relaxation process arises from the small-scale translational motions of atoms which are hindered in its metastable atomic solid-like islands.
