Low Temperature Structural Relaxation of Metallic Glass (Fe₅₅Ni₄₅)₇₈Si₈B₁₄

摘要: 使用Bordoni型儀器測量了Fe—Ni基金屬玻璃在結構弛豫過程中內耗和模量的變化,詳細地研究了在低于500K的低溫階段模量的變化。結果表明,結構弛豫對溫度的特性可劃分為兩個階段:低溫結構弛豫,主要由TSRO控制;高溫結構弛豫,主要由TSRO和CSRO控制。低溫結構弛豫的激活能約為17kJ/mol。

Abstract: A Bordoni-type system is used to measure internal friction and modulus of Fe-Ni based metallic glass during structural relaxation.Particularly,the changes in modulus have been studied in details at low temperature below 500K. The results show that the structural relaxation against temperature may be divided into two steps:the low or high temperature structural relaxation is governed by TSRO or by both CSRO and TSRO. The activation energy of low temperature structural relaxation is about 17kJ/mol.
