摘要

A reverse process design method is established in this paper by reversely applying the Hodgson recrystallization models. The method allows a draft schedule to be designed according to the requirements of the resulting microstructure, and it is made up of the design equations of process parameters and the criteria-selected values of the parameters. First, the microstructural evolution is summarized as five paths, and the temperature and strain are set to fixed ranges according to the authors experience. The mathematical models of the other parameters for each evolution path are established by applying the Hodgson recrystallization models. Secondly, criteria are established to select suitable values as a better draft schedule from uncountable groups of values. Finally, some examples are given and experiments are carried out according to the method. Metallographic observations showed that the final grain size was consistent with the design goals. The maximum relative error comparing the design goal was just 5.5%. These results prove that the method is sufficiently accurate and effective.
