The ductile/fragile character is a characteristic of materials that describes how they behave when subjected to external forces. A material is neither completely ductile nor brittle but follows a unique curve (the ductile-brittle transition curve) where the character of its deformation varies depending on the temperature. One method of checking the ductility of materials is the impact test. With the help of such a test, mechanical characteristics such as tenacity, resilience, elastic limit and yield limit, as well as hardness, ductility and ductile/brittle transition temperature can be checked. This transition temperature represents the limit temperature to which a material can be subjected to in order to preserve its mechanical properties.
