Abstract

Pore structures and aluminum foam densities are strongly influenced by the particle size of TiH2 powders. In this paper, TG curves of the the original powders and the 4 kinds of powders which were separaed by the original powders were researched. The foaming process and pore structures using selected TiH2 powders were also systematically researched. The results show that the smaller the particle size of fractions the sooner the particles start to release hydrogen. Big particles have concentrated gas releasing time and high expansion rate, small particles have more stable foaming process. No2*(38 m~48 m) with the perfect banlance of hydrogen utilization rate and foaming stability has the optimal pore structure and maximum expansion volume. Pore strctures of precursors using selected TiH2 powders are all better than unseparated ones.
