Abstract

The shear modulus and enthalpy relaxation in a deformed Zr₆₅Cu₁₅Ni₁₀Al₁₀ metallic glass has been investigated. It has been established that inhomogeneous plastic deformation leads to a decrease in the unrelaxed shear modulus and a change in its relaxation kinetics upon subsequent heat treatment. An analysis of the calorimetric data shows that inhomogeneous plastic deformation leads to the accumulation of an additional internal energy in the metallic glass, which, however, causes no shear modulus relaxation.

Zr 65 Cu 15 Ni 10 Al 10金属玻璃在不均匀塑性变形后的剪切模量松弛和热效应

摘要

研究了变形Zr ₆₅ Cu ₁₅ Ni ₁₀ Al ₁₀金属玻璃中的剪切模量和焓松弛。已经确定，不均匀的塑性变形会导致未松弛的剪切模量降低，并在随后的热处理中改变其松弛动力学。对量热数据的分析表明，不均匀的塑性变形导致金属玻璃中积累了额外的内部能量，然而，这不会导致剪切模量松弛。
