Influence of Macroscopic Stress on the Vickers Hardness
Journal of the Society of Materials Science, Japan, 1967 Hardness value is taken as one of the most important fundamental characteristics of materials. It has been reported, however, that the hardness of metals is influenced by the existing applied or residual stress in materials and so the hardness value measured under stressed state is vague in meaning.

Leveraging Deep Neural Networks for Estimating Vickers Hardness from Nanoindentation Hardness. [PDF]
Materials (Basel), 2023 This research presents a comprehensive analysis of deep neural network models (DNNs) for the precise prediction of Vickers hardness (HV) in nitrided and carburized M50NiL steel samples, with hardness values spanning from 400 to 1000 HV. By conducting rigorous experimentation and obtaining corresponding nanoindentation data, we evaluated the performance
