Characterization of metallic samples using Charpy and pendulum scratching tests
pendulum scratching test, Charpy, toughness
One of the techniques to quantify the toughness of metallic samples is the Charpy method. However, the application of pendulum scratching test analyses to obtain properties such as toughness and dynamic hardness can be promising, due to its fast execution and low cost. Thus, the objective is to seek for a correlation between the two techniques in the characterization of the toughness of metallic materials. A comparison will be made between the Charpy method and the pendulum hammer method, including the characterization of metallic samples in both equipment and the analysis of the energy balance. By comparing the results, one can look for a strong correlation between both measured properties. So, the pendulum scratching test is expected to provide results that show a strong correlation with the results of Charpy tests performed on the chosen metallic materials. Such a correlation between significantly different properties encourages further studies that may not only explain the mechanisms involved, but also expand knowledge about the mechanical properties of materials.
