Impact Toughness

Since toughness is greatly affected by temperature,a Charpy or Izod test is often repeated numerous times with each specimen tested at a different temperature.This produces a graph of impact toughness for the material as a function of temperature.An impact toughness versus temperature graph for a steel is shown in the image.Impact Toughness - an overview ScienceDirect TopicsMaterial impact toughness can be measured by various types of test such as the Charpy V-notch impact test,Izod test or K IC test.The most commonly used test is the Charpy impact test (see Fig.6.9),which gives an indication of the toughness of a material at a specified temperature.It is not a particularly accurate test but can give a general indication of the ability of a material to resist Home - MyCommitteesb) Charpy V-notch specimens shall be cooled to a temperature of 3200F (see Q.2.2.2,Items b and c) for A522,A333 (Grade 8),and A334 (Grade 8) steels for impact testing.c) The minimum Charpy V-notch impact values shall conform to the longitudinal values in Table Q-2.Table Q-2Charpy V-notch Impact Valuesa Size of Specimen (mm) 10.00
