摘要
用自行设计的流变性能测定仪测量了624钢(32MnNiMoCu)在凝固区内的应力、应变关系。建立了该钢的流变模型、本构方程并确定了流变特性参数。为开展铸钢的应力、应变和热裂纹的计算机数值模拟提供了理论基础及计算数据。
The stress-strain relation for cast low alloy carbon steel at solidification temperature has been examined by the authors' own designed apparatus for rheological properties measurement. The rheology model, the stress-strain constitutive equation and the rheological parameters therefrom of the cast steel were proposed. Thus the theoretical basis and calculating data for computerized simulation on the stressstrain relation and thermal cracking of the cast steel were suggested.
