Hardness And Impact Tests (1975)

This film discusses hardness testing methods in engineering, specifically focusing on the Brunell and Rockwell hardness tests. It explains how hardness is measured through indentation and penetration resistance, with emphasis on the correlation between carbon content and material hardness. The film also covers additional hardness tests, such as the Mo’s hardness test, and explores the concepts of ductility and toughness, including their temperature dependence. Various testing methods, including impact testing, are illustrated to demonstrate how energy loss during fracture can be quantified, leading to insights into material properties.
