Description: This interactive exercise provides "virtual" experimental measurements to check validity of Hall-Petch relationship on Al - 4.5%Mg alloy. Samples with a range of different grain sizes d has to be prepared first. They will be annealed to go through full recrystalization process. Experimental measurements of the variation of grain sizes and Vickers hardness will be done after that. Hardness measurements can be converted into yield stress σ values, and it can be checked whether well-known Hall-Petch relationship is valid for this alloy. Before performing the actual experiment, a datasheet is provided to print and record the results.
Keywords: yield stress • hardness • grain size • Hall-Petch relationship
