CALCULATION METHOD OF DWTT TEST BETWEEN DUCTILITY AND BRITTLENESS BY IMAGE ANALYSIS

摘要

The present invention relates to a ductile and brittle specimen quantification method of DWTT Using Image Processing Technology,; In the ductile brittle and quantification method of a DWTT test, and storing the image data by photographing an image of the specimen 14, the power to the A-channel light (11) applied to the ON-to-file (FILE A) and; B power is supplied to channel light (12) to the ON step of storing the image data by photographing an image of the specimen 14 to the file (FILE B) and; Characterized in that the two to obtain a difference image of image formed, including the step of surface generates a composite image data file (FILE C) to process the data file to flexible in composite image data file (FILE C) and calculating the area of ​​the brittle surface to, and; It makes it possible to automate the results of DWTT tests that rely on the subjective judgment of the operator and quantify them, improve the testing process and the reliability of the results and to provide adequate reproducibility by providing an effective testing methods and high over them clean steel products in the production process, the certification process and provide a more effective sales process that represents a valid test results.
