| Abstract: | The effectiveness was studied by adding different kinds of viscosity increaser into Al melt. The effect of method of increasing Al melt viscosity on foam structure and the mechanism of viscosity increasing were also investigated by macroscopic observation and microcosmic examination. The results show that, after the addition of calcium, magnesium, Al_2O_3 powder and fly ash into Al melt, the material phases are changed and the existence form of viscosity increaser and the mechanisms of viscosity increasing are also different. Meanwhile, the Al foams obtained have also much difference in their structure. |
