Effects of the Al content on pore structures of porous Ti–Al alloys

Microstructure and mechanical properties of gamma TiAl based alloys produced by combustion synthesis + compaction route

“…A remarkable feature of the mixtures is their ability to evolve a large amount of heat during the interaction. However, due to low caloricity of reaction between Ti and Al, the classical SHS reaction between these two metals can be initiated only upon preheating of the green mixture [21][22][23][24][25][26][27][28][29][30][31][32].…”

Synthesis and characterization of porous Fe–25 wt.% Al alloy with controllable pore structure

“…The relationship among the permeability, the maximum pore size, and the open porosity can be described by verification of Hagene-Poiseuille equation [15]: Fig. 10.…”

“…So FeAlbased functional materials such as cellular filter not only broaden their applications, but also make the mechanical properties not an important issue. Our recent studies [14][15][16] have demonstrated that porous Fe-Al and Ti-Al structures can be fabricated through reactive syntheses of commercial Fe and Al or Ti and Al mixed powders based on the Kirkendall effect and used for the filtration purposes. The aim of this paper is to report a detailed study of the influence of the preparation parameters on the synthesis of porous FeAl alloy, in order to obtain the optimal parameters to synthesize porous FeAl alloy with controllable pore structure.…”

Effect of pressure on pore structure of porous FeAl intermetallics

“…Given the linear relationship between average pore size d and maximum pore size d m with d m = LÁd, where L is the proportionality factor, Eq. (1) can be rewritten as follows [3]:…”

“…Porous intermetallics, which include Ti-Al, Fe-Al and Ni-Al, have been fabricated in our previous work by reactive synthesis using element powders as raw materials [1][2][3][4]. Among the new porous materials with B2 structure, porous FeAl intermetallics present certain unique physical, chemical and mechanical properties.…”
