Resumen:

Steel is a material that, depending of the chemical composition and subsequent processes, can show an extraordinary complexity in terms of microstructure. This complexity in terms of microstructure makes the steel a very versatile material, but at the same time, understand mechanical properties at a microstructural scale requires nontraditional techniques. The nanoidentation is a technique that can measure hardness in a nanoscale order (10-9m); this allows reaching specific microconstituents who cannot be analyzed using conventional hardness tests. For this work, different heats of a commercial low carbon steel wire were used. The different phases present on the samples were identified and characterized using the nanoidentation technique together with X-ray Energy Dispersion, Optical and Scanning Electron Microscopy. Force-displacement curves for the microconstituents present in our material were obtained as result of this study. Copyright © 2018 MS&T18®
