This paper deals with the deep drawing of C-rail experimental benchmark, which has a complex deformation path. The influence of various lubricants, including the dry friction, low and high viscosity mineral oil, semisolid grease and PTFE film on the drawability of dual-phase steel sheets, was performed. The digital image correlation technique was applied for component tests as well as the deformation analysis. The drawability was experimentally assessed by comparing surface roughness, thickness reduction, and springback of drawn component. The experimental results indicate that the interfacial lubrication between tools and work-piece plays an important role on the drawability of advanced high strength steel sheets. The quality of component was improved obviously by using PTFE film compared to the other lubricants.
