FULL ENCLOSED DIE FORGING METHOD, FULL ENCLOSED DIE FORGING APPARATUS, AND PRODUCT OF FORGING |
摘要 |
<p>A full enclosed die forging method utilizes a forging material which comprises crystal grains of different phases and whose recrystallization temperature is T1 and whose melting point is T2. And, while the forging material is enclosed in a die, the forging is carried out by a punch to the forging material in a temperature range not less than T1 and not higher than (T1+T2)/2. Thus, the dynamic recrystallization is promoted to be able to obtain complicated shaped products with high plastic workability. <IMAGE></p> |
