1基于BP神经网络的硼铸铁等离子熔凝硬化层性能预测显示文摘采用等离子技术对硼铸铁进行熔凝处理,利用SEM、XRD及显微硬度计对硬化层的组织和性能进行了测试和分析。在此基础上,采用BP人工神经网络建立等离子工艺参数与硼铸铁熔凝硬化层性能之间的神经网络预测模型。结果表明,熔凝层的组织为细小均匀的共晶莱氏体+少量未溶石墨,神经网络预测的硬化层深度和硬度值与试验值相对误差小于4.3%,说明该BP神经网络模型可以较准确预测硼铸铁等离子熔凝硬化层的性能。利用该模型可为实际生产中选择合适的工艺参数提供参考。彭竹琴 李俊魁 卢金斌 2015金属热处理2015,40,5:2
2Prediction of Tensile Properties and Optimization of Electromagnetic Casting Process Parameters in ZL114A Alloys Using Artificial Neural Network and Orthogonal显示文摘Aluminum alloys'properties are sensitive to the electromagnetic casting process parameters very much,which have nonlinear interactive relationship with electromagnetic casting process parameters.In this study,a model was developed for the prediction of the correlation between electromagnetic casting process parameters and tensile properties in aluminum alloys using artificial neural network(ANN).The inputs of the neural network were electromagnetic casting process parameters.including electric field,magnetic field and pouring temperature.The outputs of the model were the tensile properties.including ultimate strength and elongation.The optimal results achieved from the integrated ANN and orthogonal were tested by using experimental results.Consequently,it can be suggested that the combined approach of ANN and orthogonal provides a novel way with respect to the optimization of processing parameters in the field of materials scienc.GUO Zhi-hong QU Shu-wei 2012Journal of Iron and Steel Research(International)2012,19,S2:0
