基于MBN的酸洗钢再结晶率和屈服强度表征研究
Characterization Reserch of Recrystallization Rate and Yield Strength of Pickling Steel Based on MBN
摘要
Abstract
Microstructure and yield strength,the important quality inspection indexes of pickling steel materials,are generally determined by destructive tests in industry.Magnetic Barkhausen noise detection technology can reflect the electromagnetic properties of ferromagnetic materials,while the microstructure(such as recrystallization rate,grain size and dislocation density,etc.)determines the electromagnetic properties of materials.This study carries out electromagnetic non-destructive testing of pickling steel samples in a steel plant by magnetic Barkhausen technology.By improving the Barkhausen detection system and combining with BP neural network,the recrystallization degree and yield strength of pickling steel materials are characterized.关键词
