The choice of material impact testing machine
Factors impact test machine and material of the relevant:
The different impact testing machine made of different materials impact test, test machine. However, according to different user selected material is different, the following is the influence of materials on the impact machine:
The material chemical composition, microstructure, grain size and whether the cracks, slag, segregation, white spots and non-metallic inclusions such as exceed the standard of metallurgical defects, defects or thermal treatment process in the affected manufacturers properties of samples, this is the impact testing machine is widely used in large, distributed and the impact test results. Therefore, the experimenter can through the material properties of understanding, analysis, to determine the accuracy of test results.
The factors that affect the accuracy of the results of Charpy impact test, from the material itself, specimen cutting and preparation, sample analysis, the shape and size of the impact test machine requirements, briefly discusses several main factors and temperature control. Through the test method standard, various factors affecting the Charpy impact test results can be defined, the test results are also has the accuracy and comparability
