The closed-cell aluminum foam was fabricated by direct foaming in melt. Through sampling aluminum foam in different stages the cross-section of them were observed and analyzed. It was explained how TiH_2 was decomposed after entered into the melt, how initial bubbles were formed and what was the state that generated bubbles and undecomposed TiH_2 lay in.

In order to illustrate the phenomena occurred in the technological experiments, the infiltration dynamics of liquid aluminum into porous media was simulated in accordance with the laws of similitude. The results show that (1) the relation between the displacement of infiltration front and the advancing time is 〓;(2) the pressure of infiltration changes with time according to 〓;(3) the distribution of pressure in the direction of infiltration length is P=a〓+b〓L.(4) the change of temperature or viscosity of molten aluminum affects infiltration velocity in fillers of diameter in the range of 1. 5～5. 5mm very little, but this velocity in fillers of diameter 0.5mm is reduced with the decrease of AL temperature.
