| Abstract |
The repressing treatment of the debound part was introduced in MIM of sieve size Fe powders in order to improve the densification and shape stability. The sintered density of the MIM part increased with increasing the applied pressure in repressing step, and mechanical properties of MIM were improved by additional pressing of brown part. Such a post debinding treatment was also proven to influence positively the shape stability of MIM part. The effect of the additional pressing on other MIM processes was further investigated and discussed. |
