Charpy Impact Test Lab Report
In the material testing laboratory a charpy impact test was performed on three different types hot cold and steel alloy of steels testing each variety at four different temperatures 32 c rt 100 c 0 c and 22 c.
Charpy impact test lab report. The other name of the charpy impact test is the charpy v notch test because of the specimen used in this test cut at a certain depth in v shape. The second week is devoted to the analysis of fracture surface morphology of the charpy impact samples as a function of temperature and alloy. Charpy test result can indicate how brittle the materials are. This experiment test two types of steel.
Above results are witnessed this statement. The most common methods of measuring impact energy are the. Moreover lzod impact specimen only has a v notch specimen while charpy impact specimen has both u notch and v notch specimen. Impact testing machines india.

Charpy impact test lab report. Impact test is an important test in metallography. The charpy impact test used to determine the resistance capacity of metal steel specimen against sudden impact load of a pendulum which swung from a certain height. Charpy test izod test a metal may be very hard and therefore very strong but yet be unsuitable for applications in which it is subjected to sudden loads in service.
Ksi and cvn is the standard charpy v notch impact test value. Ductility and the brittleness are affected by the temperature of the metal specimen. This is a two week laboratory. The test measures the impact energy or the energy absorbed prior to fracture.
Specially in manufacturing field impact tests are done to certify the quality of the manufacturing product. If the dimensions of specimens are maintained as indicated in standards notched bar impact test results are affected by the lattice type of materials testing temperature thermo mechanical history chemical composition of materials degree of strain hardening etc. These data and experiment 8 data are combined for the team report. The first week will focus on charpy impact testing using astm e23 type a specimens.
The charpy impact test is also called as the charpy v notch test is a standardized high strain rate test which determines the amount of energy absorbed by a material during fracture.
