本文以Gleeble-1500为实验手段,研究了ZG15CrMoV和35钢在500—1400℃温度范围内的力学行为,结果表明,两种钢在高温下表现出越来越强的时变特征,应用系统辨识理论,以实验数据作为系统的输入—输出响应,确立了两种钢在高温下的力学行为可以较好地由一个五元件流变模型[M]=[H_1]—[H_2/N_2]-[N_3/S]予以描述,通过研制的流变模型和参数辨识软件,对ZG15CrMoV和35钢在上述温度范围内的流变参数进行了辨识,辨识结果与实验结果均能较好的吻合。

Mechanical properties of steels ZG15CrMoV and 35 in the temperature range of 500 to 1400℃ have been experimently researched by means of Gleeble-1500.The experi- mental results is used as input-output responses,a rhelological model with five elements of the mechanical behaviour of steels ZG15CrMoV and 35 at elevated temperatures, i.e[M]=[H_1]-[H_2/[N_2]-[S/N_3],is determined by a system identification method,and the parameters of the model in the temperature range are also identified.
