Definitions

  • the method for producing a magnesium alloy plate material according to the present disclosure can produce a magnesium alloy plate material having excellent plastic workability at room temperature and having low strength anisotropy.
  • the mL / mC preferably further satisfies 0.95 or more and 1.25 or less, and particularly preferably 0.95 or more and 1.20 or less.
  • the mL / mD preferably further satisfies 0.95 or more and 1.15 or less, and particularly preferably 0.95 or more and 1.10 or less.
  • the average crystal grain size of the structure is preferably, for example, 2 ⁇ m or more and 7 ⁇ m or less.
  • the magnesium alloy plate 1 is excellent in plastic workability. Further, the magnesium alloy plate material 1 tends to improve its strength by work hardening. Further, the magnesium alloy plate 1 can have a uniform elongation.
  • the average crystal grain size is 7 ⁇ m or less, the magnesium alloy plate 1 is excellent in plastic workability and strength at room temperature.
  • the average crystal grain size is further preferably 3 ⁇ m or more and less than 7 ⁇ m, and particularly preferably 4 ⁇ m or more and 6.5 ⁇ m or less.
  • the total rolling reduction Rt after rolling of the nth pass, which is the final pass, is preferably, for example, 50% or more and 90% or less.
  • Total rolling reduction Rt is calculated by ⁇ (t b -t a) / t b ⁇ ⁇ 100.
  • t b is the plate thickness of the treated material 61 before rolling.
  • t a is the thickness of the rolled material 62 after the end of rolling.
  • the total reduction rate Rt is further preferably 60% or more and 90% or less, and particularly preferably 70% or more and 90% or less.
  • Example No. Sample No. 1 to sample No. 16 The magnesium alloy plate material of each sample was produced in the same order as the above-mentioned manufacturing method of the magnesium alloy plate material through a casting step, a first heat treatment step, a rolling step, and a second heat treatment step.
  • Rolling process In this step, the treated material was rolled to produce a plate-shaped rolled material.
  • the rolling process was performed by using a rolling apparatus provided with a pair of rolling rolls arranged vertically and vertically, and inserting a processing material between the rolling rolls.
  • a rolling apparatus provided with a pair of rolling rolls arranged vertically and vertically, and inserting a processing material between the rolling rolls.
  • a rolling roll For each rolling roll, a roll having the same diameter as each other and having a rotation axis not eccentric and located at the center of the roll was used. The rotation speed of each rolling roll was the same.
  • the rolling process was performed in a plurality of passes.
  • FIG. 10 is a diagram for explaining how to obtain the total angle. Therefore, in FIG. 10, for convenience of explanation, the region surrounded by the contour lines 901 having a relative strength of 2.0 and the region surrounded by the contour lines 902 having a relative strength of 5.7 are shown in a simplified manner. It does not match the pole figure shown in 8 and 9.
