Effect of Annealing on Strain Rate Sensitivity of Metallic Glass under Nanoindentation

Metals, 2020
The influence of isothermal annealing on the strain rate sensitivity (SRS) of a Zr-based bulk metallic glass (BMG) was investigated by nanoindentation. A more positive SRS is observed with a decrease in the content of the free volume (FV) of the sample ...

The strain-rate effect of engineering materials and its unified model

Latin American Journal of Solids and Structures
The test data of metals, brittle materials and polymers in high, medium and low strain-rate range were summarized. It was found that the dynamic strength or yield stress of these materials was not sensitive to strain-rate in the low and high strain-rate ...

Effects of the strain rate in compression of electrodeposited gold micro-pillars toward the design of MEMS components

Micro and Nano Engineering
In this study, the strain rate dependence in yield strengths of electrodeposited gold micro-pillars is evaluated for the design of movable components in MEMS devices. The micro-pillars are fabricated from electrodeposited gold by focused ion beam system.
