MICROSTRUCTURE AND ITS MANUFACTURING METHOD |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a microstructure having high dimensional accuracy, and its manufacturing method. SOLUTION: This manufacturing method of the microstructure 5 has a process for forging a raw material 4 by a metal mold 1. Rockwell hardness (HrC) of at least a pressurizing surface in the metal mold 1 is set to 20 or more, and a Young's modulus is set to 1 x 10<SP>5</SP>MPa or more, and tensile yield strength is set to 981 MPa or more.
