WebAlternatively, tests are carried out at a range of temperatures in order to generate a ductile to brittle transition curve. Charpy tests show whether a metal can be classified as being either brittle or ductile. This is particularly useful for ferritic steels that show a ductile to brittle transition with decreasing temperature. A brittle metal ...
