Strain Rate Sensitivity of a TRIP-Assisted Dual-Phase High-Entropy Alloy
Frontiers in Materials, 2018 Dual-phase high-entropy alloys (DP-HEAs) with transformation induced plasticity (TRIP) have an excellent strength-ductility combination. To reveal their strain-rate sensitivity and hence further understand the corresponding deformation mechanisms, we ...

Strain-rate sensitivity of glasses
Journal of Non-Crystalline Solids, 2014 AbstractWe report on the loading-rate dependence of localized plastic deformation in inorganic covalent, metallic, ionic and superionic glasses. For this, the strain-rate sensitivity is determined through instrumented nanoindentation in a load-controlled strain-rate jump test. Through relating the strain-rate sensitivity to the reduced temperature, the
