Charpy Impact

Charpy Impact - Chapry Impact testing (CVN samples) are for determining a materials toughness or impact strength. In real life situations there would need to be a notch or flaw present with the fast loading conditions that apply to impact testing. This is a fast destructive test that tests a materials ability to resist that impact loading situation. The testing can be performed at high and low temperatures. CMS has the ability to test from elevated temperatures of +400 to  -320 degrees Fahrenheit. Charpy Impact specimens are etched for notch location in weld, fusion line, and HAZ (Heat Affected Zones) of welded samples.
