Understanding Material Hardness by Emanuel Pataquiva is a document available to read on EtoBox.
This document reports on an experiment to analyze the hardness of lead samples subjected to different heat treatments. Three lead samples were tested: an initial sample, one subjected to annealing, and one subjected to tempering. The samples were tested for hardness using Rockwell and Brinell hardness scales. The results showed that annealing increased the hardness and strength of the lead compared to the initial sample. Tempering, which was done to reduce excess hardness after heating, decreased the hardne
