| Abstract: |
| The residual stress measurement of roller is very difficult because that the roller has gigantic volume, the surface is out of order and especially there are oxide film and microcrack. In order to test the veracity of the method of the critical refracted longitudinal wave measurement (CRLWM) , the CRLWM method, the X radial method and the dead hole method were employed to test the residual stress, and the test result of this three methods was compared to evaluate reliability and validity of CRLWM. The result shows that the result of all of the test method is consentaneous. |
