Rapid Measurement of Texture for Cold Rolling Interstitial Free Steel Sheets

The principle of rapid measurement texture based on an X-ray two-dimensional detector was described. The advantages of the two-dimensional detector were the ability to collect several incomplete pole figures simultaneously and to calculate the orientation distribution function rapidly. It was found that a complete texture in one sample can be measured in a few minutes and the accuracy of the orientation distribution function was not basically affected when the two-dimensional detector was fixed at an appropriate diffraction angle and the sample rotation was reduced reasonably. This is illustrated by an example of interstitial free steel sheets texture measurement. It is believed that the method can be used to develop a technology for online texture measurement of interstitial free steel sheets as well as other metal sheets in industry.
