摘要：
In this study, the influence of variables, including friction coefficient and initial blank temperature, on the formability in the hot stamping process of steel was analyzed. The formability indexes have maximum thickness thinning rate and springback. The friction coefficient is chosen between 0.05 and 0.4. The range of initial blank temperature varies from 825 to 995 degrees C. The combination of central composite design and response surface method was used to analyze the relationship between the variables and indexes. The maximum thinning rate of the hot formed part increases obviously with the increase of the friction coefficient. The maximum thinning rate increases slightly with the decrease of the initial blank temperature. The springback increases with the decrease of the friction coefficient significantly. The initial blank temperature affects the springback slightly.
