High Damping Related To Anelasticity Of Mn-Cu-Alloys
AI summary Read the abstract
This study investigated the dynamic relaxation spectrum and micro-plastic behavior of three Mn-Cu alloys across a broad temperature range (-293 to 973 K), characterizing amplitude-dependent internal friction across three deformation amplitude zones. The results identify dislocation-based mechanisms of hysteretic damping and micro-plasticity in these high-damping alloys.
The dynamic relaxation spectrum of tree Mn-Cu alloys for a broad temperature interval -293-973K is investigated in order to determine the micro-plastic behavior of the material at levels of relative deformation at the range of 10 -4 -10 -2 .The amplitude dependence of internal friction (IF) shows presence of tree zones of deformation amplitudes and possible dislocation mechanism of hysteretic damping and micro-plasticity in material.

Amplitude dependence of the internal friction in a Pb-62% Sn alloy
AI summary Read the abstract
The amplitude-dependent internal friction of a Pb-62% Sn alloy was measured across its microplastic and superplastic states using flexural vibration, and a phenomenological model treating plasticity as a hybrid relaxation-hysteresis process was developed. The cyclic strain-hardening exponent was found to differ significantly between the microplastic and superplastic regimes.
Scaling Effects in Reversible Microplastic Strain
AI summary Read the abstract
This study analyzed reversible microplastic (anelastic) strain as a function of stress amplitude and temperature using non-linear internal friction measurements in various materials. The research examined both dislocation-related and twin boundary-related anelastic behavior, revealing scaling effects in the reversible microplastic strain response.
Evaluation of Microplastic Flow Stress in Copper Alloys from Amplitude-Dependent Internal Friction
AI summary Read the abstract
Microplastic flow stresses in eight copper alloys with dilute solute additions were evaluated from amplitude-dependent internal friction measurements. The results show that different alloying elements affect dislocation-solute interactions differently, providing insight into the atomistic mechanisms of solid solution strengthening in the microplastic deformation regime.
Anelastic and Microplastic Damping of an Mg–Zn–Y–Al Alloy
AI summary Read the abstract
This materials science study analyzes damping behavior in a magnesium alloy, focusing on anelastic and microplastic deformation mechanisms at varying strain amplitudes. This paper concerns metallurgical microplasticity (small-scale metal deformation) rather than environmental plastic pollution and is not relevant to microplastic contamination research.
Temperature dependent measurement of internal damping of austenitic stainless steels
AI summary Read the abstract
This paper measured internal damping of austenitic stainless steels (AISI 304, 316L, and 316Ti) as a function of temperature using resonance methods, finding that microplastic processes and energy dissipation are closely tied to defect content. The measurements were used to characterize elastic properties, stress relaxation behavior, and the effects of second-phase particles and voids.
