Sažetak
In order to improve the quality of people ‘s travel and improve the performance of travel insulation cup, the thermal deformation behavior of 304 stainless steel, the edible grade material of travel insulation cup, was studied by Gleeble- 3800 thermal / mechanical simulation machine. The true stress-strain curve of 304 stainless steel was obtained by hot compression test with deformation temperature of 800~1 100 °C and strain rate range of 0,001 ~ 1 s-1. According to the real stress-strain curve, the Arrhenius constitutive model of 304 stainless steel was constructed. The results show that the flow stress of 304 stainless steel increases with the increase of deformation temperature and strain rate. The theoretical stress value predicted by the constitutive model is fitted with the experimental results, and the correlation is 0,995, indicating that the model has high prediction accuracy.
