TiH₂ content, mixing, pressing, different mold filling rate as the factors which affect foaming process on the powder metallurgical route were investigated. TiH₂ was added in the amount of 0.5-1-1.5-2 wt% to adjust the proper amount. Differential scanning calorimetry tests were conducted on the TiH₂ powders in order to obtain optimum hydrogen releasing condition. Aluminum and TiH₂ powders were blended with the different speed-time combination. The mix was compacted at different pressures with the aim of explaining of the oxide layer deformation. An acceptance-rejection criterion was developed and used in pore analysis. Also, the using of a borosilicate glass molding technique are completely original and a new approach.
