摘要： PROBLEM TO BE SOLVED: To provide a precision forging method of magnesium alloy, which causes work softening in a material by generating dynamic recrystallization in a magnesium alloy material during forging and secures excellent shape accuracy even in a forged product having a complicated shape by adequately arranging an air vent mechanism.
SOLUTION: A punch 6 is structured so as to be divided into a shaping part 7, a spacer 8, and a punch holder 9 in a direction orthogonal to a pressurization direction. An opening 13 for forming a deformation part 12 is penetratingly arranged at the shaping part 7, and an air vent groove 21 allowing air to be vented in an outer circumferential direction is formed at a surface which is the opposite side of the shaping part of the spacer. A communication groove 24, which enables a part allowing air at the shaping part side of the predetermined spacer not to be vented to communicate with the air vent groove of the spacer, is formed corresponding to a position of an unfilled part 22 for the material flowing in the opening part. When the material made flowable by the work softening due to the dynamic recrystallization of the magnesium alloy stored in a die is filled into the opening by the pressurization of the die, air in the unfilled part is made to be vented outward through the communication groove and the air vent groove.

摘要： PROBLEM TO BE SOLVED: To provide a forging method capable of carrying out forging which does not generate crack or breakage even at a low temperature by maintaining or increasing hydrostatic-pressure stress without executing conventional strong strain forming performed as a pretreatment of forging of magnesium alloy and without changing an aspect of shearing deformation caused by plastic deformation during forging.
SOLUTION: Before plastic deformation, magnesium alloy material M in a dent portion 4 for shaping a product is made in a restrained state at an area other than the openings 6 of the dent portion 4 for shaping the product which forms deformed parts 5, so that it is placed under an environment where the hydrostatic-pressure stress in the workpiece is apt to increase simultaneously with the start of pressurization. The openings 6 of the dent portion 4 for shaping the product have a shape which does not have a folding part, so that the aspect of the shearing deformation caused by the plastic deformation is not changed during shaping and friction restriction of material flow during forging is promoted. By this way, the hydrostatic-pressure stress in the magnesium alloy material M is increased.
