Charpy impact test - Wikipedia

The Charpy impact test, also known as the Charpy V-notch test, is a standardized high strain-rate test which determines the amount of energy absorbed by a material during fracture. This absorbed energy is a measure of a given material's notch toughness and acts as a tool to study temperature-dependent ductile-brittle transition. It is widely ...

Charpy toughness of historical swords? BladeForums

Mar 19, 2016 · From the graphs in the ASM metals handbook, for quenched and tempered carbon steels of carbon content typical of good swords of that time (about 0.6-0.7%), Charpy impact energies are 11-15J at room temperature. 0.8%C is 9J, and 1095 will be lower than that. 440C hardened to 57HRC, all of 2J. 440A should be about 8J.
