Charpy impact sample processing method for Charpy impact test

Abstract

The invention provides a Charpy impact sample processing method for a Charpy impact test, which is applied to the technical field of dynamic mechanical property test methods. The Charpy impact sample processing method for a Charpy impact test comprises the following processing steps that when the cross section of the Charpy impact sample is in single-side welding or double-side welding with the cross section similar to the single-side welding after cutting, a straight line b1 is parallel to the upper and lower surfaces of the impact sample, the distances between the straight line b1 and the upper and lower surfaces are equal, and the straight line b1 intersects with a fusion line at a point A; the straight line a1 passes through the point A and is perpendicular to the upper and lower surfaces of the Charpy impact sample, and the position of a1 is taken as the central line position of the notch of the Charpy impact sample. The Charpy impact sample processing method for the Charpy impact test can effectively solve the problem of positioning the processing position of a Charpy impact sample notch of a material at a weld joint fusion line in the Charpy impact test recognized by an existing welding process, ensures that the Charpy impact test is reliably carried out, and is accurate and reliable in test result.

Description

technical field [0001] The invention belongs to the technical field of dynamic mechanical performance test methods, and more specifically relates to a Charpy impact sample processing method for Charpy impact tests. Background technique [0002] The Charpy impact test is to use the principle of energy conservation to break a Charpy impact specimen of a specific shape and size processed in accordance with relevant standards under the action of an impact load to determine a dynamic mechanism of impact energy absorbed during the fracture process. Performance test method. The Charpy impact test has become the most widely used traditional mechanical property test to measure the toughness of metal materials because of its simple sample processing, short test time, and test data sensitive to material structure and metallurgical defects. It is one of the important methods for the toughness of materials under impact load, and it is also the most important test method for testing mate...
