We investigate the role of aging temperature on relaxation of internal friction in Zr59Fe18Al10Ni10Nb3 metallic glass. For this purpose, dynamic mechanical analysis with different annealing temperatures and frequency values is applied. The results indicate that the aging process leads to decrease in the dissipated energy in the temperature range of glass transition. It is also found that the increase in applied frequency weakens the loss factor intensity in the metallic glass. Moreover, the Kohlrausch–Williams–Watts (KWW) equation is used to evaluate the evolution of internal friction during the aging process. According to the results, higher annealing temperature will make the primary internal friction in the material increase; however, a sharp decline is observed with the time. The drop in characteristic time of internal friction is also closely correlated to the rate of atomic rearrangement under the dynamic excitation so that at higher annealing temperatures, the driving force for the collaborative movement of atoms is easily provided and the mean relaxation time significantly decreases.

Zr59Fe18Al10Ni10Nb3金属玻璃在不同时效温度下的内摩擦行为

我们研究了时效温度对 Zr 59 Fe 18 Al 10 Ni 10 Nb 3内摩擦松弛的作用金属玻璃。为此,应用了具有不同退火温度和频率值的动态力学分析。结果表明,老化过程导致玻璃化转变温度范围内耗散能降低。还发现应用频率的增加削弱了金属玻璃中的损耗因子强度。此外,Kohlrausch-Williams-Watts (KWW) 方程用于评估老化过程中内摩擦的演变。结果表明,较高的退火温度会使材料的一次内摩擦增大;然而,随着时间的推移观察到急剧下降。
