Charpy temperature
WebFigure 2-1: Charpy impact tester, sample positioned in anvil and general testing results. This test has been used almost exclusively with -centered-cubic (bcc) crystalline body materials. These materials show a transition from ductile to brittle behavior with temperature (Figure 2-2). This means that at low temperature the fracture energy is low.
