Chapter 2 – Effects of Processing and Temperature on Charpy Impact Toughness in Metallic Glasses and Metallic Glass Matrix Composites Introduction to Charpy Testing Charpy impact testing is a(CIT) n ASTM standard fracture mechanics technique used to measure a material’s notch toughness at moderately high strain rates. It is defined by the ASTM From the three creep settings, elapsed recovery strain values were similar, as were the Charpy impact test data from corresponding VPPMC samples; i.e. there were no significant differences in .
The objective of the Charpy impact test to ISO 148-1 is the determination of the impact energy and determination of the impact strength of a metal. The test indicates whether the metal is tough or brittle. In addition, the tough/brittle transition can be determined based on the temperature. Impact strength is a material characteristic value.
