Impact Testing of Metals
Abstract Impact testing of metal experiment was conducted by performing Charpy V-notch impact tests and the ductile-brittle transition temperature of the three metallic samples was established. Three samples of metals were studied ( 1018 hot-rolled steel, brass and aluminum) to assess the Charpy V-notch impact energy as a function of temperature and the ductile-brittle transition temperature. The DBTT for the sample tested were recorded as follows: -109F, 32F, 71F, 140F and 205F respectively. From the results obtained, it is evident that the fracture energy varies with the original temperature of the specimen under investigation. For Steel, the highest fracture energy ...
