| Abstract: | The purpose of the research is to obtain an effective method to predict the hot ductility of low-carbon steels, which will be a re ference to evaluate the crack sensitivity of steels. Several sub-netwo rks modeled from BP network were constructed for different temperature use, and the measured reduction of area (AR) of 12 kinds of low-carbo n steels under the temperature of 600 to 1000℃ were processed as trai ning samples. The result of software simulation shows that the model e stablished is relatively effective for predicting the hot ductility of steels. |
