Impact and toughness measurement of metals
Witryna6 mar 2024 · The Charpy impact test was conducted at room temperature to evaluate the impact toughness of the weld metal treated by different PWHT process … WitrynaA metal may possess satisfactory toughness under static loads but may fail under dynamic loads or impact. As a rule ductility and, therefore, toughness decrease as the rate of loading increases. Temperature is the second variable to have a major influence on its toughness. As temperature is lowered, the ductility and toughness also …
