Abstract：

By considering the theoretical analysis on heat transfer process of hot tools in hot FLD test, the heating-cooling temperature reflecting-controlling system for hot forming dies and sheet were designed, and a hot FLD test platform for TC alloy sheet in high temperature environment was established. Based on this hot FLD test system and the hot FLD test process, the temperature variations of TC alloy sheet were obtained and analyzed at the test temperature of 650, 700 and 750 ℃. Furthermore, the hot FLD test of TC alloy sheet at 700℃ was performed. The temperature verification results show that the temperature variation is less than ±10 ℃, and the system reliability is confirmed. Based on the above results, the FLD experimental data of TC alloy sheet at 700 ℃ condition was obtained.
