METHOD FOR CONTROLLING CRYSTAL GRAIN OF METALLIC MATERIAL |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a method for locally controlling the size of crystal grains at a desired position of a metal material. SOLUTION: The method for controlling the crystal grain of the metallic material includes application of a laser beam at a predetermined position of the metal material. The output of the laser beam is 20-40 W, the energy density is 4.2×10<SP>7</SP>to 8.4×10<SP>7</SP>W/cm<SP>2</SP>, and the time of application of the laser beam to the predetermined position is≤25 seconds.
