Liquid Mechanism of Molten Metal Alloys for Metallic Foam |
| 초록 |
The rheological characteristics are the most important factors in the metal foam manufacturing. One of the possible process-routes is to blow gas bubbles into liquid metals. However many metallic foams produced by foaming method have coarse and irregular cell structures. One of the industrial aims is to fabricate foams with more uniform structure and cell size. It is important to understand the mechanisms and the factor control. Therefore in this research, the rheological characteristics, namely surface tension (by the ring method) and viscosity (by the rotation method) of Al alloys were investigated under pure Ar atmosphere in function of temperatures and alloying element concentration. Of course in the actual foaming process the appearance of the rheological characteristics are very much influenced from the existing of particles. However the fundamental rheological data do not lose the importance. |
