Abstract
To solve the problems of low efficiency, high cost, difficulty in controlling microstructure and performance of thin-walled titanium alloy components during hot forming, the cold-die hot stamping forming technology for titanium alloy attracted much attention in recent years. In this new technology, the heated titanium alloy sheet is rapidly stamped and cooled in the die by using the room temperature die. Due to the elimination of the die heating, the forming efficiency of titanium alloy thin-walled component is transformationalloy improved and the cost is reduced. However, different from the traditional isothermal forming, the temperature of titanium alloy sheet decreases continuously during cold-die hot stamping forming process, which brings a new challenge to the control of titanium alloy forming limits, springback, microstructure and performance. The characteristics and problems of cold-die hot stamping forming technology for thin-walled titanium alloy components were analyzed, the effect laws of rapid heating on the microstructure and performance of titanium alloy were summarized, the development of rapid heating process for thin-walled titantium alloy components and the future development of this technology was prospected.
