| description | PROBLEM TO BE SOLVED: To provide a metal member forming method, a metal member, and a metal member forming device for achieving the forming property and higher strength of the metal member. SOLUTION: The cylindrical metal member 1 having a hollow chamber 10 and a forming die 3 having a forming die face 31 are used. The metal member 1 is heated to a quench-strengthening temperature zone (e.g. A1 transformation temperature or above). By increasing the internal pressure of the gas in the hollow chamber 10 of the heated metal member 1, a wall 1a of the metal member 1 is swollen (plastically deformed), and the swollen wall 1a of the metal member 1 is brought into close contact with the forming die face 31 of the forming die 3 to perform the forming and the quench-strengthening. The wall 1a of the metal member 1 is hardened, and the strength of the metal member 1 is increased thereby. |
